Ecovacs Deebot T30 Omni: Two-minute review

If you’re after an all-in-one robot vacuum cleaner – one that vacuums, mops, and then cleans itself by also washing and drying its mop pads – you’re typically looking at a rather premium price point. The Ecovacs Deebot T30 Omni offers you all of that, but without that high cost. And it doesn’t necessarily make too many sacrifices on features either, which really highlights how much bang for your hard-earned buck it can offer.

Depending on where you live, there might be two versions of the T30 Omni available – a white Pro model and the black non-Pro edition that’s reviewed here and is available in the UK and Australia. Strangely, neither model is currently listed on the US Ecovacs website. The only difference between the two, other than their color, is the Pro model gets three additional features: Ecovacs’ Yiko voice assistant, a dirt-detection deep-mopping mode and an onboard camera. I missed none of these during my time testing the standard T30 Omni, although some users might find the deep-mop function useful.

The first thing that got my attention was just how compact – or rather squat – it is compared to other all-in-one robot vacuums that come with two water tanks in the cleaning station. Ecovacs says the T30 Omni (and its Pro version) will fit under any kitchen or bathroom counter – while my under-counter cabinets weren't designed for such a scenario, measurements indicate that if I were to make small changes to how they're structured, it would take minimal carpentry to get the robot vacuum and its dock stowed away neatly. The rest of the design is also very well considered and I think it’s one of the better-looking full-featured robot vacuums I’ve seen.

It doesn’t disappoint in its performance either. With four suction levels and four water-flow rates, there are a lot of custom routines you can set up for the T30 Omni. What I appreciate even more is that even at its highest suction setting, the robot isn’t as loud as I’ve previously encountered with other similar models, even those from Ecovacs. The maximum suction here is 11,000Pa, which isn’t as much as other premium models available on the market, but it’s more than enough for most homes. However, if you have carpets that are particularly dirty with tangled hair or fur, it will have trouble sucking those up in their entirety. What hair and fur it manages to clean thankfully doesn’t get entangled around the main bar brush, making ongoing maintenance easy.

Also aiding in making the user lazy is how well it washes its mop pads after each cleaning session. You can choose how often you want the pads to be washed and how long you want to set the hot-air drying for. And that’s a good thing because those mops can get dirty – during my testing, I found the mopping to be so effective that the pads would get brown within minutes! I had no idea how much dust my hard floors could pick up! Better yet, the extendable mop pads ensure even the edges of my rooms were cleaned well, although the occasional corner can be missed.

The tanks are remarkably easy to refill or clean out, and so is the base tray that the mop pads are washed on. And while you can always bend down to press a button in a pinch to start or stop the T30 Omni, it will also respond to a light kick to the bumper.

All in all, I think this is a really good all-in-one robot vacuum cleaner, able to give even more expensive models a run for their money, making this a really great-value investment if you want to stop spending time on vacuuming and mopping your floors. Where there’s scope for improvement is with the Ecovacs Home smartphone app, but only marginally.

Ecovacs Deebot T30 Omni review: Price & availability

• Available since 2024 in UK and Australia; not sold in the US
• List price: £799 / AU$1,749
• Often discounted during major sales

Announced in May 2024 for most major markets, the Ecovacs Deebot T30 Omni is now listed for purchase in European countries, including the UK, and in Australia. Strangely, it’s no longer listed on the official Ecovacs website in the US, although it was announced for the American market.

At full price, the T30 Omni will set you back £799 / AU$1,749 but it’s often discounted to a much lower price, which makes this a truly worthwhile investment given its power and feature set. For instance, at the time of writing, it’s available for £699 directly from Ecovacs UK, while it’s dropped as low as AU$1,199 in Australia.

Other similar models can cost you around the £1,000 / AU$2,200 mark: for example, the Dreame L40 Ultra available in the US and the UK with the same 11,000Pa suction has a list price of $1,499.99 / £999 (unavailable in Australia), but take it up a notch and the 12,000Pa Dreame X40 Ultra with detachable mop pads will set you back a whopping $1,899 / £1,299 / AU$2,799. Similarly, the Eufy Omni S1 Pro, with its interesting slimline design but with a maximum of 8,000Pa of suction costs $1,499 / £1,499 / AU$2,699.

There are, of course, cheaper robot vacuums but, given how well the T30 Omni balances power, performance and price, it represents very good value for money even at full price.

Ecovacs Deebot T30 Omni review: Specs

Ecovacs Deebot T30 Omni review: Design

• Standard T30 Omni model only available in black; white is the Pro model
• Not as tall and heavy as other all-in-one robot vacuums
• Extendable mop pads that automatically rise to avoid carpets

Whether you opt for the standard T30 Omni in black or the white T30 Pro Omni version, the only physical difference between the two is the color – everything else is identical from a design perspective. Neither, however, come with any additional replacement parts, which is a glaring omission on Ecovacs’ part as you are immediately faced with having to purchase additional dust bags at the very least. Thankfully you won’t find the need to replace the mop pads too soon as the washing mechanism is fantastic, although keep an eye on them as, like any fabric, they will begin to show signs of wear and tear.

Lack of some replacement parts aside, the entire appliance, despite its plastic build, is quite solidly made. You’ll find no need for the user manual to set up the various parts of the robot vacuum’s dock – it’s all very intuitive and just slots into place. Once assembled, it doesn’t look like most other all-in-one robovacs – it’s shorter and looks more compact, although it has a similar footprint to other models. This compactness in height is what allows the T30 Omni to slot under a counter if you are able to fit it in.

Unlike other such all-in-one robot vacuums, the water tanks – clean and dirty – aren’t placed inside the clean station, but are an essential part of the dock, sitting atop the enclosure housing the 3.5L replaceable dust bag. From an aesthetic standpoint, I like that the translucent clean-water tank sits in the front, and it means you can see when a refill is needed. Both tanks have a 4L capacity, meaning they’ll last a few cleaning sessions before you need to manually do anything… although I don’t like having any dirty water in the tank for more than a day, so I’ve always just cleaned it out, but that’s just me. And I’m also appreciative of the fact that the dirty water tank is opaque and sits at the back of the machine.

Ecovacs has even put some serious thought into the design of the washing tray that the actual robot sits on to charge and have its mop pads washed. It reminds me of old ribbed washboards from the 1800s, with raised ridges that ensure the mop pads get a good scrubbing after (or during) each mop run. The tray is also very easy to remove and clean out.

Overall, I’m a big fan of the slightly voluptuous-looking clean station and how easy it is to get to any part of it to refill, clean or replace, although I can also see why some people may not like the look compared to the straight lines of other models.

The robot itself isn’t very different from the familiar round droid we see from most brands. There’s the usual lidar turret on the top to house Ecovacs’ proprietary TrueMapping 2.0 technology, while the top panel has three function buttons: zone cleaning, start/pause and exit/return to base. Combination presses of these three buttons can also be used but, from my experience, the only time you’ll really need any of them is at the initial setup process.

The top panel of the robot also simply lifts off to reveal the 300ml rectangular dust bin inside. You won’t, however, see the water reservoir, which is hidden under the opaque plastic.

On the front of the robot you can clearly see the obstacle avoidance system – called TrueDetect 3D 3.0 – on either side of which are distance sensors. Two contact points for charging are also visible on the rear of the robot, as well as the water inlet for filling the reservoir and the hatch to self-empty its dust bin. The front bumper is also sensitive to a light kick, which tells it to either start or pause wherever it is.

The underside of the robot has four anti-fall sensors along the rim, and there’s also a sensor that detects carpets. There’s one side brush, while the main bar brush has been redesigned to offer zero tangles when hair and fur is being vacuumed. I have to admit, I was rather skeptical about the ZeroTangle brush, but I’m quite impressed with how well it manages to remain free of all entanglements. The two rotating mop pads are affixed to the removable plastic supports via some seriously strong Velcro but, unlike more premium machines from Samsung and Dreame, the mop pads don’t automatically drop if you set the robot up for just a vacuum run. They do, however, extend outward to wash room edges and can rise up to 9mm to avoid carpets and rugs.

Ecovacs Deebot T30 Omni review: Features

• Up to 80% more suction power compared to the T20 Omni
• Spot cleaning improvements based on user feedback
• Foot-touch start/pause functionality

You’d think that, to keep costs down, the T30 Omni would be missing key features, but Ecovacs has managed to pack it full of the things you really need and left out anything that you wouldn’t necessarily miss – like voice control. The one thing that I do wish I could have tried is the deep-clean mopping mode that the Pro model has but, honestly, I didn’t necessarily feel any FOMO while testing the standard T30 Omni.

One feature I’m a massive fan of, and it’s actually a rather superfluous one, is the foot-touch start/stop functionality. What that means is giving the robot a light kick on the bumper makes it start or, if it’s already moving, stop where it is. I admit to being lazy and this makes my need to bend or reach for my phone unnecessary when I just need it to stop for a minute or two when I have to step in its path for whatever reason. I hands-down agree that it’s a novelty, but it’s the kind of fun feature I love.

Importantly for a robot vacuum, Ecovacs has upped the ante where suction is concerned. Compared to the Ecovacs Deebot T20 Omni’s 6,000Pa suction power, the T30 Omni now boasts a much better 11,000Pa. For its price point, this is a fantastic upgrade.

Another feature worth mentioning here is the reimagined spot-clean functionality that is now also available on other top-tier Ecovacs robovacs. At the press of the spot-clean button on the top of the robot, the T30 Omni will know to clean a 1.5m x 1.5m square area around wherever it’s located at the time. If it’s at the dock, it will clean around the dock; you can pick it up and place it anywhere in your home and it will begin the spot clean there. It’s a handy feature to have for those quick spills that need immediate attention.

One useful feature that’s not quite unique to the T30 Omni, but is effective nonetheless, is extendable mopping. This allows the mop pads to either remain extended at all times or automatically pull out when the robot senses a wall or furniture close by. This works so well that even thin furniture legs are identified and the mops can clean right alongside them and, where possible, move a full circle around them.

Other features include Bluetooth connectivity for easier setup and the Ecovacs Home app widget for iPhones and Apple Watches for getting a whole-house clean going instantly.

Ecovacs Deebot T30 Omni review: App control

• Cleaner app than before but still scope for improvement
• A number of custom ‘Scenarios’ can be set up
• Editable map, but adding furniture is fiddly

I’ve reviewed quite a few Deebots over the last few years, some of which have been discontinued. So it’s fair to say I’ve seen the evolution of the Ecovacs Home app to its current form, which is arguably the best it’s ever been. It’s a lot cleaner and easier to use, although I still see scope for improvement. That said, in the few months that I’ve been testing the T30 Omni, I’ve not had a single app-related problem.

The Ecovacs Home app has everything you need to set up the T30 Omni if it’s your first Deebot, including giving it a name. In my case, I called the robot vacuum Dirt Vader. To get started, you can set the robot to do a mapping run which doesn’t take too long. It quite literally rolls through your home in a slightly random manner and picks up where the walls and doors are to create a basic map. This you can then edit in the app, adding names to the various rooms and even furniture. While it’s really easy to partition rooms, adding furniture is annoying as placements are not necessarily going to work on a flat 2D space.

The app displays all the cleaning options clearly, including the various combinations of vacuum and mopping, and how often of both you want the bot to do. You can choose the suction power and the water-flow rate.

You can set up what Ecovacs calls Scenarios – different cleaning runs to suit different needs. For example, I have one called Daily Clean, which is a single vacuum run throughout my home at the highest suction. Another one that I call Deep Clean is two vacuum runs in the carpeted bedroom, followed by two mop-after-vacuum sessions in the rest of the house with hard floors. I have another called Quick Clean, which is a single vacuum-and-mop run on only the hard floors (so it skips the bedroom). The options are plenty, giving you a lot of control over your floor-cleaning routine.

The app also lets you change the volume of the voice prompts of the robot which, by default, is really rather loud. You get the usual cleaning logs and you can also keep track of when you need to replace parts like brushes, mops or the dust bag. Setting up schedules is also there.

You’ll get voice prompts and an app notification if the wash tray needs cleaning in the middle of a session – that’s because the mop can be set to be cleaned at regular intervals. I had mine set to every 15 minutes, so Dirt Vader would go back to the dock a couple of times during most cleaning sessions to wash the mops. I really do not like brown streaks on my light-grey tiles.

My only issue with the app is with the Scenarios tab: only two Scenarios are visible on most phone screens, but the Manage option gets in the way of the second listing. It’s also not immediately clear that you just need to slide to view all the different Scenarios. I’d also like the map to be a bit more detailed, but that’s not really a complaint, but an observation.

• App control score: 4.5 / 5

Ecovacs Deebot T30 Omni review: Performance

• Hardly ever misses mopping a room edge or along furniture legs
• Excellent vacuuming prowess on hard floors
• Can struggle on excessively dirty carpets

We have quite a few Deebot reviews on TechRadar, and one thing they all have in common is their good performance. And that’s again the case here. In fact, I was rather impressed by how quickly, and accurately, the T30 Omni mapped out my apartment – it took just six minutes to do so and all walls, doors and floor types were correct even though it seemed to move rather randomly. It doesn’t account for furniture, but you can see the vague shapes in the basic map. Subsequently, I didn’t have a single issue with navigation either – Dirt Vader always moved in a clear pattern within each zone, hardly ever missing a spot.

Whether it’s just vacuuming, just mopping or both together, the T30 Omni does a very fine job indeed. During testing, I sprinkled some talcum powder on the floor to see how it would cope with such fine particles and, set to do a spot clean with vacuum and mop together, I was pleased that I couldn’t see white powder when I ran my fingers over the area.

While the side brush did scatter some grains of rice while vacuuming, a second run cleared those up as well. A few scattered grains that went into a corner did get left behind though, but I can’t blame Dirt Vader for a shoddy job – even my Dyson V15s Detect Submarine would have a hard time getting at those grains with the Fluffy Optic or the Digital Motorbar. I’d have to use the Crevice Tool for that. Perhaps the Dyson 360 Vis Nav, with its protruding tongue, might have picked up the stray grains… Or for situations like that, Ecovacs has another solution in the form of the Deebot T30S Combo, which packs a handheld cordless vacuum along with the robot.

Dirt Vader’s vacuum prowess is also quite good on carpets and rugs… provided the carpets aren’t already too dirty. Only the bedroom in my apartment has wall-to-wall carpeting and, over the duration of a week, my hair gets all over it. If there’s too much hair, I found that the T30 Omni set at max suction over two consecutive runs can struggle to do a deep clean. There were always some strands still visible, but it was along edges where it truly struggled to gather tangled hair. However, my medium-pile rug in the living room, which doesn’t get too dirty, always looked refreshed after a single vacuum run at max suction. On hard floors, reducing the suction to Standard or Strong is more than enough for a good clean.

Mopping is where the T30 Omni shines. When Ecovacs says ‘edge mopping’, it’s truly the case here. The extendable mop pads are effective at cleaning right along the 90º angle of a wall and where furniture legs meet the floor. No matter how thick or thin a leg might be, I saw Dirt Vader go a full 360º around the vertical axis where the height under furniture allowed it to go.

During my testing, I tried various water-flow rates and, for the kind of tiles I have in my apartment, the High setting was the best for a regular clean, so that is what I set it to for every Scenario. This saw all dusty footprints disappear in one mop session, as did a splatter of hot sauce on the kitchen floor. However, a thick, dried-up blob of mayonnaise took a couple of goes before it was cleaned up.

Getting the bin to auto-empty at the Extra setting meant that it was fully emptied, with only the barest film of dust along the plastic sides still visible, which can be washed out if you prefer, but I found no need to do so. The self-washing of the mop pads is also fantastic. After nearly three months of using Dirt Vader, the mop pads didn't look too worse for wear.

What I love even more than its ability to clean is how quietly it goes about its business of cleaning. Given I’ve regularly used it at its maximum suction, I’ve never really needed to increase the volume on my TV while it was doing its thing. And my TV is in the bedroom where it’s cleaning only carpets, so the suction is always on. Ecovacs says it hits a maximum sound level of 65dB, but that’s only when it’s auto-emptying. That’s still relatively quiet compared to other self-emptying models. While vacuuming at maximum suction, it’s only ever hit 57dB for me, measured using a smartphone app, so do take that number with a pinch of salt. Still, it’s one of the quieter robot vacuums I’ve tested.

• Performance score: 4.5 / 5

Ecovacs Deebot T30 Omni review: Battery life

• Uses a 5,200mAh capacity lithium-ion battery
• Rated for up to 290 minutes on a single charge
• Can take up to 6.5 hours to top up an empty battery

Ecovacs has always endeavored to provide good battery life for its robot vacuums and, again, the T30 Omni delivers. Even with max suction and high water-flow rates set up for two mop-after-vacuum runs, Dirt Vader always had an average of 35% battery life still left after covering an area 74sqm. That isn’t bad at all.

It’s also intelligent enough to know how much battery it needs to finish an incomplete cleaning session if it does ever run out of power. This happened during one session, when I started my Deep Clean scenario (two vacuum sessions in the bedroom, plus two mop-after-vacuum runs in the rest of the apartment) when the battery was at 82% when it began. Instead of waiting till it was a full 100%, Dirt Vader charged till about 55% and finished the job it was meant to.

That meant I didn’t have to wait the full six hours for it to top up to 100%, which is how long Ecovacs says it can take the T30 Omni to fully charge up from empty. However, I can’t really vouch for that as I’ve not had an opportunity to see it fully drained after completing a cleaning run (even the one time mentioned above, where it charged just enough to finish an incomplete Scenario).

• Battery score: 5 / 5

How I tested the Ecovacs Deebot T30 Omni

• Used in my own home for about three months
• Tried various settings and created different cleaning routines
• Scattered various common grains, powders and liquids to test cleaning

While I've had the Ecovacs Deebot T30 Omni for a few months for testing, there was a period of 4 weeks where it was switched off from the mains while I was overseas. Unlike some other connected devices that may need repairing to your smartphone after such a long time of inactivity, the T30 Omni remained paired and started up as if it wasn't lying dormant at all.

During the three months of actual testing, I used the T30 Omni in my one-bedroom inner-city apartment at least once a week, trying out various permutations and combinations of vacuum and mop. Given I have a mix of both carpets (in the bedroom) and tiles (rest of the apartment), it was easy to test the T30 Omni's cleaning prowess. I scattered powders, grains and sauces on the floor to see how it performed, plus I made a note of dusty footprints on the living room floor that came from a rather dirty balcony.

I kept tabs on how well the mop pads were washed and dried after each clean, and checked the dust box inside the robot to ascertain the docking station's suction. Practically every feature of the robot vacuum was tested for this review, including the foot-touch start/pause function.

I have previously tested several other Ecovacs Deebot models, as well as robot vacuums from other brands, putting me in a great position to compare the T30 Omni's performance and features.

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.

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.

Dreame X40 Ultra: Specifications

Dreame X40 Ultra review: Design and features

• Automatically detachable mop pads
• Base station with auto empty and mop clean
• Extendable side brush and mop pad

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.

• Design score: 4 / 5

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.

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.

Base station performance

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.

Dreame X40 Ultra review: App control

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

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.
