• Some Google smart speakers recently stopped responding to questions
• Users reported the problem with a variety of different devices
• Google investigated, and says the issue should now be fixed for most users

If you've noticed that your Google Nest smart speaker or hub appears to be ignoring voice commands, you're not alone – but Google says it has identified the problem, and is rolling out a fix to stop your devices giving you the silent treatment.

The problem was highlighted by, among others, Rita El Khoury of Android Authority, who returned from her Christmas vacation to find that her Google Nest Hub and Google Nest Audio would no longer respond to requests to tell her the weather. She was able to use the speakers to control her smart home devices, but functions like setting timers were hit and miss.

She wasn't alone, and it seems those two devices weren't the only products affected. Several other device owners have reported similar problems on the company's support forums.

"All of my Nest speakers suddenly got dumb; all were working, but as of yesterday, they all freeze up when I [try] to get past 'Hey Google'." explained Thom Drewke, who found himself faced with a similar issue. "That is, 'Hey Google are you there' gets a response, but 'What's the weather' gets no response. All of my speakers did this at the same time. Bizarre!"

Another person explained that they had nine Google Home speakers – a Google Nest Hub Max display, and a mix of various first-generation devices – and all of them had stopped responding to questions.

"I have a lot of devices connected to Google Home and I can control all of them still, I just can't ask certain questions," they wrote. "I have tried rebooting the google home devices, I have tried rebooting the router a dozen times and still nothing."

Hey Google...

Google was quick to act, and told Android Authority via email that although its team was still investigating the root cause of the problem, it had resolved the problem "so all users should be up and running now".

That should come as a relief to anyone who's looking forward to the arrival of Gemini for Google Assistant, which should allow your existing smart speakers to give you more comprehensive answers – but only if they're willing to talk to you.

• Unofficial renders of the iPhone SE 4 have emerged
• The phone is expected to look a lot like the iPhone 14
• Apple may decide to rebrand the device as the iPhone 16E

If the leaks are to be believed, Apple will be launching the iPhone SE 4 – or should that be the iPhone 16E? – in March, and we now have some unofficial renders of the handset to give us an idea of what it's likely to look like.

These come from concept renderer @kanedacane (via Android Headlines); they're not leaked images of the phone itself, but rather an educated imagining of how the iPhone SE 4 will look based on all the information that's leaked out so far.

To sum it up: this phone is expected to look more like the iPhone 14 than the iPhone SE 3 (both of which were launched in 2022). For the first time, the SE series is set to ditch the old Touch ID look and lose the home button.

It should make for a sleeker, more modern-looking smartphone, as these renders show. Reading about the changes to the iPhone SE 4 is one thing, but seeing them is quite another – and these renders are likely to be pretty accurate.

All change

As you can see from the unofficial renders above, the iPhone SE 4 is expected to come in white and black options, matching the shades that the current model is available in (there's also a Product Red version of the iPhone SE 3).

There's lots more to talk about when it comes to the iPhone SE 4 besides the redesign. The leaks suggest that the device will have a single rear camera, as well as a new Wi-Fi and 5G chip that's been manufactured by Apple (and which should mean better battery life).

We're also expecting to see the A18 chipset and 8GB of RAM inside the iPhone SE 4, making it powerful enough to cope with the demands of Apple Intelligence. What with the new materials and bumped-up specs, we might also see a modest price hike this time.

As for that rumored rebranding to the iPhone 16E, we'll have to wait and see. It sounds like a somewhat clumsy name, but it would bring the phone into line with the iPhone 16 series, and would mirror what Samsung has done with the Galaxy S24 FE.

Meta is dreaming of its social platforms brimming with helpful AI-generated profiles and content fueled by the models underlying Meta AI, according to recent comments by Connor Hayes, vice-president of product for generative AI at Meta in an interview with the FT.

Of course, logging onto Facebook and seeing a "user" named Clara_ChefBot_9000 posting AI-generated pie recipes might sound like a great way to drive engagement to Facebook's bosses, but it isn't quite the same as scrolling through your Aunt Susan’s baking photos. Regardless, Meta's vision of a platform brimming with relatable AI personalities is already beginning to roll out and if that doesn’t make you want to power down your devices and take a walk outside, let's look closer at what this might actually entail.

The charm of social media has always been people. The whole point is seeing people sharing their lives. The oversharing, humble bragging, and dumb arguments about pineapple on pizza can irritate you, but at least you're rolling your eyes about real people. AI-generated profiles, no matter how sophisticated, will always lack that authenticity. Sure, Clara_ChefBot_9000 might be able to generate recipes, but she’ll never know the joy of burning her first batch of cookies or the embarrassment of a recipe flop posted to a very judgmental audience.

Then there’s the issue of trust. We’re already grappling with deepfakes and AI-generated misinformation, not to mention people sharing a curated view of their lives as artificial as any algorithm. Do we really need bots with profile pictures trying to convince us of their “personal” opinions? Imagine arguing with a bot about politics, sports, or the aforementioned pizza topping, only to realize it’s been programmed to needle you into buying a product.

Meta AI is expanding everywhere. (Image credit: Meta) AI optimism

When AI assists humans in creative efforts, it can pull off some amazing feats, but when AI tries to mimic human creativity, it rapidly becomes dull slop or simply nonsense. Do we really need our newsfeeds clogged with bots sharing AI-generated memes or supposedly relatable status updates? And that's if they don't just go off the rails with errors. Imagine a feed full of AI profiles posting “Happy Mother’s Day” in the middle of November.

Meta AI can be fun (especially once you know how to turn it off), and there's real value in an AI capable of entertaining you with conversation. Maybe Clara_ChefBot_9000 can offer you some cooking tips at midnight. That's not a real, human connection, though. A chatbot might tell you how to bake a souffle, but it won’t commiserate with you when it collapses.

Meta might argue that these bots could help users with practical tasks, but that doesn't mean there should be a million AI characters on the platforms. Social media platform SocialAI is attempting to sell people on that idea. Its mobile app connects each user only to AI chatbots they are supposed to interact with; they won't encounter other humans there. That might be okay in limited contexts, but it makes no sense for Facebook or Instagram.

Social media exploded because it was a fantastic way to connect with people and make friends. AI can’t completely replace that. Instead of filling the platform with fake users, Meta should focus on enhancing the experience for the real ones. Otherwise, they risk creating a digital ghost town.

LG XBoom Go XG8T review: two-minute review

The LG XBoom Go XG8T has a pretty tough task – standing out in a field with extremely strong competition from some of the biggest names in audio. That’s right, this large portable speaker finds itself pitted against some tough rivals from the likes of JBL, Bose and Ultimate Ears. So, how does it fare in its battle for supremacy?

Well, firstly, LG has looked to focus on this speaker's design – specifically its phenomenal durability. The LG XBoom Go XG8T is said to have "military grade" protection against the elements, having passed seven different durability tests. It also has an IP67 waterproof rating and high-quality build, protecting it against impact and underwater submersion.

As well as that, this has neat, customizable LED lights, an attractive wraparound speaker grille and conveniently adjustable handle/strap. It's looking good so far, right? Well, I hate to be the bearer of bad news, but outside of its looks and design, the LG XBoom Go XG8T really struggles to outdo some of its similarly-priced competitors that have made our list of the best Bluetooth speakers.

There are some standout reasons for that. First, battery life. This is the XG8T's fatal flaw. LG says you get up to 15 hours of playtime – but there’s a real emphasis on the ‘up to’. If you’re playing at 50% volume without EQ adjustment or LED lights, sure, that might be attainable. But with lighting on and the booming Sound Boost feature activated, you’re going to see that battery percentage fall way faster. 15 hours isn’t particularly impressive anyway, so given depletion happens much faster with core features like Sound Boost is a real shame.

Next, let’s talk sound – another area where the XG8T can’t quite usurp some of the best waterproof speakers around. Bass, thankfully can get pretty deep and hits with impact, especially with Sound Boost on. Generally, elements like vocals and percussive elements in the treble range are clear too, although you may sense a bit of harshness at top volumes. However, this isn’t going to offer a massively detailed listen and there are no fancy audio codecs – think LDAC – to play with, so you end up with solid, yet fairly unremarkable sound in the end.

There are a couple of other smaller issues that arise too: slightly outdated Bluetooth connectivity, lacking EQ presets and a hefty AC adapter stick out. When you combine all of that with a high list price of $379.99 / £400 (about AU$600) it’s hard to justify buying this portable speaker.

Having said that, there’s another factor to consider. Since it’s release, the XG8T has frequently been available on sale, sometimes even for around half price. This, of course, changes the game significantly. Is the battery life still a big issue? Sure. But the power and bass on offer here would certainly be a lot more impressive in this context. So, if you can grab it at a massively cut price, it could possibly be worth considering the XG8T.

But all in all, this speaker just misses the mark. It’s not by any means a bad option, with impressive low-end power, generally clear all-round audio and incredible durability. But unless you’re a massive LG fan specifically, you’re likely to be better served elsewhere. Some of 2024’s big hitters like the Bose SoundLink Flex and JBL Xtreme 4 are regularly on sale for well under the list price of the XG8T and they are some top alternatives – so why not read more about those in the ‘Also Consider’ section below…

(Image credit: Future) LG XBoom Go XG8T review: price and release date

• $379.99 / £400 (about AU$600)
• Launched in March 2024

OK, so if you buy the LG XBoom Go XG8T at its list price, you’ll have to shell out a fair amount of cash. Its usual price is $379.99 / £400 / AU$600, pitting it against competitors like the JBL Xtreme 4 and Ultimate Ears Epicboom.

However, as you may expect for a speaker that launched early in 2024, you can regularly find the XG8T available at a cut-price. In fact, this model can be as low as half price. I've spotted it going for less than $200 / £200 with some online retailers. It’s also worth noting that this speaker is only available in Black.

(Image credit: Future) LG XBoom Go XG8T review: features

• LG XBoom app compatibility
• Sub-par battery life
• Outdated Bluetooth version

The LG XBoom Go XG8T has a pretty tidy set of features and it owes this, in part, to the LG XBoom companion app. Using this, you can access some fairly typical options: multi-point connectivity, Party Link for pairing multiple speakers and EQ adjustment, for instance.

And on the topic of EQ adjustment, this app offers a pretty mixed experience. One key positive is that there’s a fully customizable, six-band equalizer available through the app, so you get a decent amount of control over the sound you get here. But I was frustrated at the real lack of presets available here. You can use Sound Boost, which provides a boost to volume and low-end power, but this counts as a preset in itself. Other than that, there’s only Standard mode. I would’ve liked to have seen some gene-specific presets, for instance, to make it easy to get your preferred sound from the offset.

Another cornerstone feature is LED light customization. There are three main categories to switch between – Ambient, Nature and Party. Within these are three preset choices, such as ‘Passion of youth’, ‘Cheerful celebration’ and ‘Gorgeous night view’ in the Party category. However, you can also save a custom pick within each of the three groups – making for a user experience that’s not only highly customizable, but highly convenient. If only EQ settings were this fully-fledged!

One more nice touch here is Healing Therapy. This provides access to a set list of calming sounds, all of which have to be downloaded separately. A few examples include ‘A Still Summer Night with Insect Sounds’ or ‘The Sleepy Sounds of the Deep Sea’, which I really enjoyed listening to. You can also set a sleep timer with Healing Therapy, just in case you find that you’ve nodded off. I think it’s fair to say that this feature is a bit of a gimmick, but gimmicks can still be fun. I still liked it, anyway.

But alas, there are a couple of issues I have with the XG8T, feature-wise. First of all, it doesn’t have the most up-to-date Bluetooth version. This speaker harnesses Bluetooth 5.1, even though a handful of speakers are already using version 5.4 now. But that’s not a deal-breaker, in my view.

The killer issue here is battery life. LG says you get up to 15 hours, that is if you keep volume at 50% or lower and have EQ and lights off. Activate Sound Boost and crank up the volume and battery depletes way too quickly. I’d lost 20% in about an hour with an average of about 50-60% volume, intermittent Sound Boost use and LED lights turned on – that’s pretty poor for a modern Bluetooth speaker of this size. So, if you want to get the best out of the XG8T, expect sub-par battery life. In fact, it may not even last an entire event without dying unless you’re conservative with volume and lighting.

• Features score: 3/5

(Image credit: Future) LG XBoom Go XG8T review: sound quality

• Impactful bass
• Mighty volume levels
• No ‘hi-res’ codecs for more detailed listening

In the audio department, the LG XBoom Go XG8T puts in a pretty solid performance, with the main attraction being… you guessed it, bass. Now, out of the box, you may feel low-frequency audio output is a touch underwhelming. Don’t get me wrong, it’s by no means pathetic, but it could definitely do with a leg up. And that’s where Sound Boost mode comes in, an essential option for bass-heavy bangers or if you want to flood large or outdoor spaces with your favorite tunes.

When listening to Voyager by Daft Punk, I was impressed by the pumping deep bass on offer, which produced a ground-shaking, head-bopping performance ideal for a party setting. The funky guitar playing throughout the track didn’t sound distorted either, even at about 70% volume. Getting higher than this was quite the task though – not because it sounds terrible, but because this thing can get very loud, thanks to its 60W woofer. And that certainly improves its credentials as a capable outdoor speaker.

One complaint I had when listening to Voyager and a host of other tracks, such as Moloko’s I Want You, was that higher-pitched percussive elements didn’t have perfect clarity and sharpness. This was emphasised more at top volumes, where this could get a bit grating – something that wouldn’t typically bother me too much, but for the price you're paying here this level of critique is valid.

Another slightly disappointing aspect of this speaker is its lack of support for more ‘hi-res’ Bluetooth codecs, such as LDAC. And this was a contributor to some songs occasionally lacking, or underplaying details in tracks. For instance, when I listened to Didn’t Cha Know by Erykah Badu, smaller percussive and string elements were kept under wraps, making for a slightly constricted listen.

Sure, vocals sounded decently balanced and overall audio was clean, but in all honesty that’s to be expected at this price-point. If you want a more detailed, nuanced listen for the money, this speaker is not your best option. You can pair it with another Go XG8T speaker (in dual mode, or multiple speakers in multi mode) via LG's Wireless Party Link, however, if you’d at least like access to even bigger sound.

Ultimately, this speaker’s success hinges much more on its talents in the bass and loudness departments. This is designed more for outdoor or party use and it works very nicely for that. Just make sure you have Sound Boost on to really add some meat in the low-end. You get great volume levels too and although things can get a little edgy at the top of the speaker’s range, it will still be capable of filling a larger room or cutting through pesky background noise in an outdoor setting.

• Sound quality score: 3.5/5

(Image credit: Future) LG XBoom Go XG8T review: design

• Military-grade durability
• Decent looks with classy LED lights
• Adjustable strap can work as handle

The LG XBoom Go XG8T has a pretty standard look about it – which is by no means a bad thing. It’s a large, black Bluetooth speaker with passive radiators on each side, lined by LED lights and a wraparound speaker grille. I found this to be an attractive looking speaker, with its build quality perhaps being indicative of a higher price point.

But this is more than a classy-looking speaker, it’s super practical too. First of all, one of the speaker’s main selling points is that it offers military-grade durability. LG says that the XG8T has passed seven tests against: dust, high temperatures, rain, salt fog, shock, vibration and water immersion. On top of that, it’s IP67 certified, so it can even survive being submerged under a meter of water for up to thirty minutes.

Another big win in terms of practicality is the inclusion of an adjustable strap. The attached strap is more of a handle at first, which is ideal for carrying this fairly hefty speaker over short distances. But let’s say you’re going for a beach trip and have to carry the XG8T over a bit more ground. Fear not! You can extend the attached strap to a considerable length, in order to sling it around your shoulder.

This speaker also has some useful button controls just below the handle. These are all well-sized and serve their purpose well. You have the obvious inclusions, play/pause, volume controls and power on/off. But there’s also a Bluetooth button to swiftly connect devices and a Sound Boost option to crank up volume and boost the low-end. On top of that, there’s a tab on the reverse side of the speaker to access the USB-A port or the charging slot.

And that leads onto the only design element that bothered me with the XG8T: charging it up. The included AC adapter gives off the vibe of an oversized laptop charger from about 15 years back – not a good look. This really juxtaposes the high practicality of every other aforementioned element – and as much as it’s no deal breaker, I would’ve preferred slightly more lightweight charging equipment for the XG8T.

• Design score: 4/5

(Image credit: Future) LG XBoom Go XG8T review: value

• List price is high
• But it's often available at a reduced price
• Outdone by too many competitors

If we are judging the LG XBoom Go XG8T’s value on list price alone, things aren’t looking too good. You’d need fairly deep pockets to pick up this speaker without a discount – for reference its official price is $379.99 / £400 (about AU$600). And this speaker doesn’t do a ton to set itself apart at that price point.

Audio, although good, isn’t massively detailed or perfectly clear all the time. Combine that with a disappointing battery life and unimpressive EQ presets and its clear: this speaker isn’t worth its list price, especially when you consider the incredible quality of competitors in this price range, like the JBL Xtreme 4 or Bose SoundLink Max (more on those in ‘Also Consider’).

But luckily, there’s more to the story here. Since its release this speaker has been heavily discounted on a number of occasions – even for as little as half price in the UK and US. Even still, it's not free of competition. There are speakers like the Tribit Stormbox Blast, for instance that offer booming, talented audio for under $200 / £200.

Even if the XG8T is a solid speaker in its own right, it's hard to justify its list price. And even at a cut-price, I wouldn’t argue it's best-in-class either.

• Value score: 2.5/5

(Image credit: Future) Should I buy the LG XBoom Go XG8T? Buy it if...

You want booming bass
I wouldn’t necessarily argue that the LG XBoom Go XG8T has the most impactful bass in the game, but it certainly offers a healthy serving of low-end power. If you’re hosting a house party or outdoor event, there’ll certainly be enough bass on offer to fill a larger space with big, booming audio.

You want ultimate protection against the elements
If durability and reliability are at the top of your priority list, this speaker is sure to serve you well. Not only does it have the IP67 dustproof and waterproof rating, but it offers military-grade protection against impact and harsh weather conditions.

Don't buy it if...

You want top-tier audio quality
If you want an elegantly balanced, beautifully detailed listen, you could do better than the LG XBoom Go XG8T. Audio quality is by no means bad here, but I didn’t get an amazing sense of nuance from this speaker, with the lack of ‘hi res’ audio codecs holding it back further.

You want a top value pick
If you’re paying the list price for this speaker, you’re not getting great value, unfortunately. Of course, it’s often available at a significantly cut price now, but there are so many fantastic, low-priced speakers out there, including the Tribit Stormbox Blast, for instance.

LG XBoom Go XG8T review: also consider

JBL Xtreme 4
For me, the JBL Xtreme 4 was one of 2024’s best Bluetooth speakers, bringing fantastic audio quality, high build quality and fantastic features to the table. When I initially reviewed it, my main issue came with its high list price, but you can regularly find it for far less now, making it a top-tier option for speakers in this size and weight class. Read our full JBL Xtreme 4 review.

Bose SoundLink Max
Another one of 2024’s big hitters was the Bose SoundLink Max – a speaker that offers punchy, agile and ultra-clean audio. It also has beautiful looks, an IP67 waterproof rating and a handy two-way USB-C socket, making it the perfect marriage of style with practicality. Read our full Bose SoundLink Max review.

LG XBoom Go XG8T review: how I tested

• Tested for one week
• Mainly used at our music testing space at Future Labs
• Predominantly tested using Tidal on the Samsung Galaxy S24 FE

(Image credit: Future)

I dedicated hours when listening to the LG XBoom Go XG8T and tried it out in a range of spaces. However, I did predominantly use it in our music testing room at Future Labs to assess audio quality in a quiet, controlled environment. I also conducted a battery test to validate LG’s claim about playtime.

When I listened to music, I mainly harnessed the power of Tidal via the Samsung Galaxy S24 FE, from which I streamed tracks within our expertly curated TechRadar reference playlist. But that's not all – I also tapped into tunes from my personal music library as well as podcast episodes. Finally, I used the similarly-sized JBL Xtreme 4 as a point of comparison across areas like sound quality, features and battery life.

Dreame X40 Ultra: two-minute review

Dreame Technologies hasn’t been around long but, since its inception in 2017, the brand has made some excellent robot vacuums, including the Dreame L20 Ultra. The X40 Ultra succeeds the older model (as well as the X30 Ultra), bringing much-improved intelligence and tracking compared to lesser bots, as well as a fairly unique collection of features. For those who want something slightly cheaper, it's well worth checking out our Dreame L40 Ultra review.

Like most robovacs, the X40 Ultra handles both vacuuming and mopping and comes with a base station that empties the robovac’s dustbin, dispenses water, and cleans the mopping system. Where it stands out is the ability to leave the mop pads behind when vacuuming, the automatic dispensing of floor-cleaning fluid, the wide array of sensors, and the ability to recognize a large number of objects using its cameras.

Getting the X40 Ultra up and running is relatively simple, and upon first activation, it will map your home with an array of sensors. The test space for this review was my own home with a built-in area of 80 sqm, and it took the bot about 10 minutes to poke its robotic nose into every room. The quality of the resulting map is excellent, and any adjustments are easy to make within the Dreamehome app. The X40 is great at identifying and avoiding obstacles like shoes or cables and can even recognize your pets and give them space when cleaning. While very functional overall, the app can be a little clunky at times, like lack of consistency in how navigation gestures work, and a convoluted layout to reach certain settings.

If activating a scheduled or single-time clean, selecting CleanGenius mode lets the robovac use its own smarts to decide exactly what is needed, and it will vacuum, mop, and go back over areas as it sees fit. While the results were good, I found the robovac went a bit overboard and wanted to mop my polished wooden floors every day. Instead, I set a schedule for a daily vacuum and reduced mopping to once a week. I also configured shortcuts in the app to trigger custom cleanups, like an extra vacuum or mop by the front or back door for when my dog walked in with muddy paws.

The X40 Ultra is equipped with an extendable and liftable side brush for getting into corners and under furniture, plus dual spinning mop pads – one of which can also protrude further out as needed. The mop pads are magnetically attached, so the bot can leave them behind at the base station when vacuuming carpets, avoiding any chance of spreading damp mop water or contamination.

After three months of daily use, it’s hard to find fault with the vacuuming prowess of the X40. It works equally well on hard floors, carpets, or rugs, and the extendable brush does a great job of getting into corners and cleaning debris from along walls. The spinning extendable mops are likewise very effective, and the X40 Ultra can keep your floors shiny or quickly get rid of sticky messes. It also very thoroughly cleans the mop pads with hot water – then dries them with hot air – to avoid odors. Overall, the wearing parts on the X40 Ultra (like the mop pads, filters, and corner brush) are fairly robust and don’t need to be replaced too often.

Importantly, it has pet feces detection – and it really does work – which allows the robovac to spot and avoid any accidents, ensuring you won’t come home to a horror show of smeared messes. It can also detect wet patches, so it won’t spread or vacuum over any puddles it encounters.

As great as the robot itself is, the suction on the auto-empty station is a bit weak. I found I had to change the bag more often than expected – and these can get quite expensive. The X40 Ultra itself is not cheap – it’s one of the more expensive models on the market – but when you compare the actual technology and features included, it provides decent value overall.

(Image credit: Future) Dreame X40 Ultra review: Price and availability

• How much does it cost? Starting from $1,899 / £1,299 / AU$2,799
• When is it available? Available to buy now
• Where can you get it? You can get it in the US, UK, and Australia

The Dreame X40 Ultra was announced in May 2024 and can be bought directly from the Dreame website if your country has a local online storefront or from authorized local retailers, which can include Amazon. It has a rather steep asking price of $1,899 / £1,299 / AU$2,799 and, so far, has only attracted modest discounts. That said, it shouldn’t be too long before we start seeing worthwhile discounts, which would make the X40 Ultra worth investing in if you want a complete and autonomous cleaning solution for your floors.

However, using the X40 Ultra will incur ongoing costs, specifically the replaceable dust bags. I’ve included the accessories pricing below for the US, UK, and Australia. Notably the Dreame website doesn’t sell the side brush in the US, or the brush cover in Australia. You can also get a kit that contains 2x dust bags, 2x dust filters, 1x main brush, 2x side brushes, 6x mop pads – rather useless ratios of these consumables as they don’t match the usage rates.

For households like mine that have people (or pets) with long hair, Dreame sells an optional TriCut brush that’s designed to shred hair and avoid tangles and clogs. This upgrade does a much better job at keeping hair from tangling compared to the standard brush, and I think it’s well worth the added $49.99 / £49.99 / AU$199.95 – though Aussie buyers pay a very steep premium compared to the US and UK.

If you don’t need all the features offered by the X40 Ultra, or have a simple home layout with few obstacles, then a cheaper robovac like the Dreame L10s Ultra or D10 Plus may be a better buy. You can also opt for options from Ecovacs, with some models like the Ecovacs Deebot N10 Plus ($649.99 / £499 / AU$999) and Ecovacs DEEBOT T20 Omni ($1,099.99 / £951.65 / AU$1,799) offering good value for money.

The X40 Ultra has a fairly standard design and complements the typical round robovac form factor with a base station for charging, dustbin emptying, floor-cleaner dispensing, mop washing and drying – plus containers for clean and dirty mop water. In the box, you get the robovac itself (including mop pads), the base station, two dust bags, a cleaning tool, and 200ml (6.7 ounces) of floor-cleaning solution. Setting it up is very easy – the base station needs the ramp attached, but otherwise, it’s ready to go once plugged in and charged. After installing the app, you scan a QR code on the robovac, and it walks you through the rest of the process in just a few minutes.

The base station is tall (60cm / 24-inches) but relatively skinny (35cm / 14-inches) and only needs 5cm (2 inches) of clearance on each side. The dust bag and floor cleaner dispenser are hidden under a front-opening cover on the dock, while the mop water is accessed from under a hatch on the top – meaning it’s not suited for placement under a bench. Dreame will also soon release an optional kit to allow the base station to be plumbed into a fresh-water supply and a waste-water outlet, enabling the mop water changes to be fully automatic. The availability of this kit is to be confirmed.

The robovac sports a multitude of sensors to help navigate your home, ensure the best clean, and avoid any pets or places where it could get stuck. The front of the bot has two cameras (one infrared), as well as 3D Dual-Line Laser sensors and LED headlights. The underside has a carpet sensor, along with downward-facing cliff sensors to detect steps or other drops. The sides of the robovac have edge sensors, and on top, it features a microphone and a laser distance sensor (LDS). All these work together to allow the bot to recognize over 120 different types of objects – including obstacles like cables that could cause a tangle when vacuuming.

The X40 Ultra offers four suction levels – Quiet, Standard, Turbo, Max, and Max+ – with up to a very high 12,000Pa of pull. Notably, the highest suction level (Max+) is only available for a one-off clean and can’t be used with a schedule or a customized shortcut clean. This means the full advertised suction (up from the X30 Ultra’s 8,300Pa) feels like marketing spin, rather than an actually useful upgrade.

The robovac can extend its side brush to get deep into corners, clean along edges or under the lip of low furniture – and even lift it to avoid spreading liquids. The bot can also magnetically drop and pick up the mop pads from the base station, giving it extra cleaning flexibility. While the bot can lift the pads when vacuuming carpet, the clearance is 10.5mm (0.4 inches), so for deeper carpet piles or rugs, leaving the mop pads behind ensures there’s no chance of dampness or cross-contamination. The right-hand side mop pad is also extendable – meaning the X40 Ultra can reach into corners, mop along the edges of kitchen cabinets, or even clean a little way under the edge of low appliances like a fridge.

Dreame X40 Ultra review: Performance

• Somewhat noisy at full power
• Amazing obstacle recognition
• Weak base station automatic emptying

Overall, the X40 Ultra does a very thorough job of vacuuming and mopping – and aside from picking up larger debris by hand and the occasional spot clean, I didn’t have to do any extra floor cleaning myself. The robovac has a CleanGenius mode that lets it choose the cleaning parameters for you – though I found it mopped much too frequently, and I preferred using the scheduled cleaning function (as well as shortcuts) to create my own customized cleaning regime.

The X40 Ultra isn’t especially fast, and during my testing, it took around 1 minute per square meter when vacuuming, and takes about the same amount of time to mop. That said, it can vacuum and mop at the same time if needed, which allows for a quicker cleaning run. The 6,400mAh battery is rated to provide up to 198 minutes of vacuuming and mopping at Standard suction strength, covering up to an area of 308m² (3,315ft²) in Quiet mode. It’s a little frustrating that Dreame rates the runtime and area coverage at different vacuum power levels – the exact amount of coverage per charge depends on your specific home and cleaning settings. During my testing, the X40 Ultra was able to vacuum my small 80m² two-bedroom home at Max suction level, then do a full mop, and still have 80% charge remaining. Extrapolating from that, I think it will have no trouble cleaning up to 200m² per charge.

• Overall performance score: 4 / 5

Mapping and obstacle avoidance

After setup, the X40 created a very accurate map of my home – with no adjustments needed in the app aside from giving rooms specific names. When vacuuming, the array of sensors and cameras does a great job of spotting anything on the floor, and it’s especially careful to stay clear of anything that might cause a tangle – like shoelaces or cords. Handily, the bot records a picture (viewable in the app) of any obstacle it encounters, making it easy to move it before the next clean.

The X40 Ultra has the smarts to recognize your pets (in my case, just the paws of a Great Dane) and will keep clear if it spots them snoozing. It records a few pictures of any interactions – viewable in the cleaning log via the app – so you can see how your pet reacts to the vacuum. It’s also possible to set up zones for the robovac to stay out of, like around a pet's bed or feeding area. Even more importantly, the robovac can recognize any pet droppings and will steer well clear when cleaning. My dog doesn’t make any messes at home, so I faked a test using food, and the X40 Ultra had no trouble identifying the fake feces and dutifully stayed well clear.

Using the app, you can also stream live video from the robovac’s main camera while it’s working, or take over and remotely steer it – though this can be a bit laggy. You can also command the bot to navigate to a specific spot in your home, use it to have a two-way conversation, or even have it automatically search for your pets and snap a picture.

Impressively, the robovac only got stuck twice in three months of testing – and both times were my fault. The first time was because it half-ingested a USB-C cable I had knocked down next to the base station, and the second was from vacuuming up a loose tile in my (very old) bathroom. In both cases, no damage was caused, as the bot knew it was stuck and waited patiently until freed.

Overall, the X40 Ultra did an amazing job of navigating my home and had no problem cleaning around always-changing obstacles – big and small – left in its way. It’s a great choice for anyone with a busy, complex home, or if you don’t want to have to worry about picking every last thing up from the floor before cleaning.

Vacuuming

I tested the X40 on polished wooden floors, as well as tiles and rugs. Aside from vacuuming every day for three months, I also performed a number of specific tests to gauge how effective the robovac is at cleaning up a variety of spills and debris types. I used flour, sand, rice, oats, dry dog food, and some dry leaves – scattered in a corner on hard floors and then on a short-pile rug.

Whether on carpet or hard floors, the flour, rice, oats, and leaves were 90% (or more) cleaned up after one pass – and fully gone after two. The dry dog food was all sucked up in one go, while the sand took three passes to capture it all (although a few grains remained on the rug). Importantly, the X40 Ultra’s side brush is relatively slow-spinning, so it doesn’t tend to flick any material away from the vacuum. Anything larger than about 10mm x 8mm (0.4 inches x 0.3 inches) will generally be recognized and avoided by the robovac, as it could get stuck behind the main brush.

I found that the standard vacuum level is fine for picking up pet fur, dust, and light debris on hard floors – but needs to be bumped up to Turbo or Max for carpets. The higher suction modes were also best for sand, heavier dirt, or chunkier debris like oats and dry dog food. This means a daily vacuum in the standard mode with a single pass will capture almost all the lighter debris in your home, but may leave a small amount of heavier debris behind. This isn’t much of a problem, as you can customize scheduled cleans on a room-by-room basis to accommodate different needs.

On lower suction levels, the sound isn’t too intrusive – and could be set to vacuum overnight – but with the suction turned up, the noise level is not far off a stick vacuum. Measuring at 1 meter (3.3 feet) with a decibel meter, the bot produced 43 dB on Quiet, 46 dB on Standard, 51 dB on Turbo, 55 dB on Max, and 60 dB on Max+. When the robovac is driving without vacuuming, it produces 41 dB, while mopping sits at 35 dB most of the time – with occasional peaks up to 45 dB when moving fast. The base station emptying the robovac dustbin hits 57 dB, while mop washing is 33 dB with peaks up to 50 dB when the water pump runs. These results are normal, but not particularly quiet – so you'll want to position the base station away from living areas where you relax or watch TV.

My home has two people who shed a lot of long hair, and in my testing, the side brush stayed relatively tangle-free – as did the main wheels and mop pads. The front roller does slowly collect hair – as does the main brush – though the TriCut brush (which is available to buy separately) is much better in this regard. Thankfully, both these areas are very easy to maintain, and the X40 Ultra’s design keeps the hair from getting sucked deeper into the inaccessible innards of the robovac.

• Vacuuming score: 4.5 / 5

Mopping

I’m not a frequent mopper at the best of times, so I started my X40 Ultra’s testing with a deep clean – then reduced the mopping frequency to once a week – and my floors have never looked better! I found it handy to turn on an extra mopping schedule during wet weather, so areas near the front and back door were kept clean of muddy shoe and paw prints.

Like its side brush, the X40 Ultra can also extend the mop pad on the right side, and I found the robovac easily cleaned areas where a handheld mop struggled to reach. The automatically dispensed cleaning solution (a bottle is supplied in the box) also helped cut through grime in a way that robovacs using plain water can’t manage.

To further test the mopping ability, I spilled two puddles of soy sauce – one of which I allowed to dry – and also smeared wasabi paste and sticky honey on a section of tiled and wooden floor. I found that the liquid soy sauce was cleaned away in a single pass, while the thick, dried soy took two passes to remove. A third pass was needed to get the floor squeaky clean. The wasabi paste and honey both took two mopping passes to fully clean up, leaving no trace behind.

The bot washed the mop pads between each test – removing any contamination from previous cleanups. That said, the X40 Ultra is not designed to mop more than a small amount of liquid, as the pads are meant for scrubbing, not sponging.

The only issue I noticed is that the strong magnet in the mop pads (used to attach them to the vacuum) tends to pick up tiny particles of magnetic dirt. It’s normal for some dirt to be slightly magnetic (due to iron content), and this accumulates on the plastic spindle of the mop pads. The mop washing process doesn’t remove this dirt – in fact, it increases wear on the base station – and the slightly rusty residue can stain the mop pads or potentially other flooring during mopping. To avoid this, regularly wipe away any residue remaining on middle of the mop pads.

Dreame rates the 3.2-liter (108 oz) dust bag in the base station for up to 75 days of use – but how long it lasts for you will depend on how large or dirty your home gets. The robovac itself has a 0.3-liter (10 oz) dust bin that is emptied by the base station as needed when full, or it can be set to empty after every room.

While I was impressed with the suction on the bot itself, the base station suction is weaker than expected. I found it didn’t always manage to fully empty the bin in the robovac, leaving debris to build up if not manually cleaned. Worse, despite all its smarts, the robovac couldn’t sense when the base station had not successfully emptied its bin – or tell that it was clogged and not vacuuming effectively. That meant it would often do an entire home vacuum while clogged and not pick up anything.

Even when the base station successfully empties the robovac’s dust bin, the low suction means the debris tends to form a clog right at the mouth of the dust bag. This clog would further reduce the suction, worsening the emptying problem. I found the situation could be somewhat alleviated by setting the base station’s auto-emptying frequency to the highest setting and occasionally manually triggering an extra empty cycle. It also helped to ensure the dust bags were very carefully installed with no folds of fabric near the inlet – or to occasionally manually shift the collected debris further into the bag. Even so, I needed to change the bags well before they were full, and I found they only lasted half as long as the 75-day rating from Dreame.

This is the main reason I would find it hard to recommend the X40 Ultra for a household with pets that shed hair (like golden retrievers or huskies) or one with a lot of debris to vacuum up – as the base station suction just isn’t powerful enough to ensure problem-free operation and economical use of the dust bags.

On the plus side, the mop washing system works very well, and I only encountered one minor downside during my testing. The base station heats water and dispenses it into the washing system, then circulates it against the mop pads while the robovac spins the mop pads against plastic scrubbers to remove any contamination. The used water is then sucked out and stored in the dirty water container, and the mop pads and cleaning system are dried using hot air to avoid any odors. The washing process is a little noisy at time, like when the pumps runs, and the drying fan does make a quiet whir for a few hours.

(Image credit: Dreame) Dreame X40 Ultra review: App control

• Deep customization of scheduled cleans
• Homescreen widgets and shortcuts
• The app is sometimes laggy and feels unpolished

Image 1 of 2

While the X40 Ultra can be controlled in a limited way using the buttons on top of the circular bot, the app is the best option for everyday use. It makes it easy to interact with the map of your home – created immediately after setup and updated during each clean – and allows you to customize cleaning sessions. The depth of control is noticeably better than competitors such as Ecovacs, and you can fine-tune much of the robot’s day-to-day operations, as well as check the comprehensive cleaning history.

I found the layout and navigation of the app frustrating at times. For example, many frequently used options – like adjusting scheduled cleans – are buried a few layers deep in the menu system, and such settings are locked out when the robovac is in operation.

In my three months of testing, the X40 Ultra only failed to start a scheduled clean once (with no discernible reason) and completed the next day's clean without a problem. The robovac will only connect to a 2.4GHz Wi-Fi network, and I found it sometimes had issues with a typical dual-band (2.4GHz and 5GHz) mesh network – like you’d find in our guide to the best mesh Wi-Fi systems. At one point, the X40 didn’t want to connect to my network, and a few times it reported low signal strength despite being right near the router. I found it much more stable to configure a dedicated 2.4GHz Wi-Fi SSID for the robovac to connect to.

While the Dreamehome app is less polished than expected for such a premium robovac, it’s not better or worse overall compared to the competition. Sure, brands like Ecovacs and Eufy offer apps that are nicer to use in many ways – but neither provides the same depth of control options, and they still suffer from lag and the occasional missed clean.

Dreame X40 Ultra review: Consumables and maintenance

The X40 Ultra comes with everything you need to get started right away, but there are only two dust bags included, along with one small refill of floor cleaning fluid. This means you need to either buy spare bags when purchasing the vacuum, or order them within a month or two. The X40 Ultra consumables (main vacuum brush, mop pads, floor cleaning solution, vacuum bags, side brush and robovac dust bin filters) are mostly only available via the Dreame website in the UK and Australia, whereas in the US they are easier to buy from Amazon than they are from Dreame.

The Dreame app keeps track of each cleaning session and provides an estimated remaining life (in hours) for the consumables and wearing parts. The estimates generally seem quite conservative, and I expect many parts – like the main brush – will last longer than rated and need less frequent changing than expected. Maintenance for the Dreame X40 Ultra is fairly simple and takes about 10 minutes a month. It’s not messy or difficult to do and mostly involves giving the robovac a check-over, dusting off the sensors, and removing any trapped hair if needed. The latter involves removing the main or side brush and simply sliding the wrapped hair off – and I didn’t have to cut any free during my testing.

Extrapolating my three months of testing to a full year, and using the remaining life estimates in the Dreame app, the X40 Ultra consumables include 10 to 12 dust bags, one filter, one side brush, a container of floor cleaner, one set of replacement mop pads, and one replacement TriCut brush – adding up to around $200 / £163 / AU$500. For a larger home, this cost could easily double or triple. Notably, in Australia (where the X40 Ultra was tested for this review), the TriCut brush is 170% more expensive compared to the US and UK – so using the normal brush saves AU$150 a year.

While using the official Dreame accessories is recommended, there are third-party consumables available from online retailers like eBay and Amazon. The best are nearly indistinguishable from the official Dreame parts, while the worst are of very poor quality and won’t work correctly. Until Dreame offers affordable bulk packs of dust bags, it’s hard to pass on third-party alternatives – provided you can find good-quality ones.

How I tested the Dreame X40 Ultra

• I used the X40 Ultra as my main vacuum cleaner for three months
• My testing space included hard floors and carpet
• I performed specific grain-size and wet-spill tests

I used the Dreame X40 Ultra daily for three months in a home with a dog and two adults. I tested the X40 Ultra on polished wooden floors, tiles, carpet, and medium-pile rugs. The weather during the test period included both wet and dry conditions. I started with an initial deep clean, followed by ongoing daily vacuuming, with mopping once or twice a week – plus extra spot cleans as needed. I tested both the automatic CleanGenius mode and customized cleans using schedules and shortcuts.

I documented cleaning performance over the testing period and conducted a range of specific tests with different debris sizes to further gauge vacuuming ability. I also tested dry and wet spills to evaluate the mopping prowess. Additionally, I strategically placed debris – including fur, leaves, and hair – in problem areas such as corners to assess the robovac’s effectiveness in daily use.

During my testing period, I changed the base station vacuum bag three times, manually cleaned the mop cleaning system in the base station, and performed the full range of maintenance checks.
