ECOVACS DEEBOT T90S Pro Omni review: five weeks in, my floors have become someone else’s problem
I’ve had the T90S Pro Omni cleaning my home for over a month, and it’s the first mid-range robot that has made me question paying flagship money
The ECOVACS DEEBOT T90S Pro Omni is a refined version of last year’s T90 Pro Omni rather than a reinvention, but the upgrades are the ones you notice when you live with it. You get 40,000Pa of suction, a roller mop that lifts and covers itself before it reaches a rug, and a dock that does more of its own cleaning. After five weeks of daily runs it has become one of the least demanding gadgets in my home. It suits busy households with mixed flooring, long hair or pets that want the robot to handle the work without regular checking. The weak spots are a black finish that shows every speck of dust and a side brush that can still knock small, light objects around. Neither comes close to being a deal-breaker.
Pros
- 40,000Pa suction with 16 L/s airflow makes rugs feel properly vacuumed rather than skimmed
- The roller lifts 15mm and a physical cover drops over it, so damp fibres never touch carpet
- TruEdge 3.0 pushes the roller out 15mm, so skirting boards get mopped and not just driven past
- The dock rinses its own tray and cleans its own dirty water tank, so it needs far less hands-on care
Cons
- The matte black plastic shows dust very quickly, which is ironic on a cleaning robot
- The side brush can still flick very small, light items (think hair ties) into the robot’s path
- The dock’s auto-empty cycle is loud, at a rated 71dB(A)

Price and availability
The T90S Pro Omni was unveiled at IFA in September 2026. In the UK, Ecovacs is currently selling it as a bundle with an accessories pack for £719. Standalone pricing varies between retailers, so it’s worth checking Amazon UK before buying. In the US, Ecovacs lists it at $799 in black or white. The UK listing currently shows only black.
The price matters here. The standard DEEBOT T90 Pro Omni now sells for £529 direct from Ecovacs UK, so you pay roughly £190 more for the S. Further up the range, the DEEBOT X12 OmniCyclone launched at £1,249. The T90S sits in a sweet spot: it costs clearly more than its predecessor and a lot less than the flagships.
Design and build
Out of the box, the T90S looks like most modern robot vacuums: a round puck with a black finish and a tall dock to match. The detail that matters is the height. Ecovacs moved the navigation sensors into the body rather than a laser tower on top, so the robot is only 95mm tall. In practice that’s the difference between a robot that cleans under the sofa and one that bumps into it and turns back. Over five weeks, the low profile has meant fewer places in my home I need to sweep myself.
The finish is my main design complaint. The matte black plastic looks smart in photos and does a good job of making the dock blend into a hallway corner. Up close, though, it picks up dust remarkably fast. It’s a bit absurd to wipe down a robot whose whole job is removing dust, but I did it more than once in the first fortnight. If the white version reaches the UK, that’s the one I’d go for.
The dock is a big object at 50cm tall and 46cm deep with its ramp fitted, so measure before you order. The good news is that you get a lot of automation for that space. The fresh water tank holds 4 litres and the dirty tank 2.2 litres, and both lift off the top. That’s much easier than kneeling down to pull out drawers. Dust goes into a 2.5-litre bag, and replacement bags cost £19 for a pack of three from Ecovacs UK.
The robot weighs 5.4kg. That doesn’t matter much day to day, since it lives on the dock, but it’s good to know if you plan to carry it upstairs to clean another floor. Two large 7.6cm drive wheels let it climb single thresholds up to 25mm and two-step obstacles up to 49mm. Door bars and rug edges have never got the better of it in my home.
Vacuuming performance
The headline upgrade is suction: up to 40,000Pa, compared with 30,000Pa on the T90 Pro Omni, and paired with 16 L/s of airflow from what Ecovacs calls its BLAST system. Suction figures are notoriously hard to translate into real life, and I’m wary of any brand that turns them into a numbers race. What I can say is that rugs no longer feel like an afterthought. Earlier robots I’ve used seemed to glide over thicker pile. The T90S feels like it’s actually working the fibres, and the dust bag fills accordingly.
Hair is where you either learn to love a robot vacuum or end up resenting it. Ecovacs’ ZeroTangle 4.0 system covers both the main brush and the side brush, and the company claims full removal of medium-to-long hair up to 30cm. I won’t repeat a lab claim as fact, but five weeks in I still haven’t had to cut a wrap of hair off the brush roll with scissors. That’s a ritual every long-haired person with a robot vacuum knows well. For me, that alone justifies a lot.
The side brush is the one area that hasn’t fully won me over. It does its job along edges, but it can be over-eager. Very small, light objects can get flicked out of position, and occasionally into the path of the main intake, even after the robot has detected them. If your floors are scattered with hair ties or small toys, a quick tidy before a run is still worth doing. That’s true of every robot vacuum I’ve tested, so it’s not a reason to avoid this one. It’s just a reminder that “obstacle avoidance” means avoiding obstacles, not keeping them perfectly still.
AIVI 3D 4.0 handles that obstacle avoidance using structured light, an RGB camera and supplementary lighting. Ecovacs says it recognises furniture, pets and loose wires. In my experience it’s been dependable at going around things rather than through them. Navigation also feels purposeful: it cleans in neat, systematic lines rather than wandering.
Mopping performance
This is where the T90S feels most special, and most of the credit goes to the roller mop. Most robot mops use spinning circular pads. The OZMO Roller 3.0 is a 27cm cylinder that presses into the floor at up to 4,000Pa. Fresh water is sprayed onto it as it turns, and a scraper removes the dirty water straight away, so the roller isn’t spreading yesterday’s kitchen grime around the hallway. Ecovacs claims this cuts smearing and water spots by up to 67%. In practice, my floors dry quickly and look clean rather than just damp.
What I didn’t expect to appreciate so much is the edge cleaning. TruEdge 3.0 pushes the roller up to 15mm sideways so it runs right along skirting boards and around furniture legs, with a soft felt strip on the outer edge so it doesn’t scrape paintwork. Edges are where a lot of mopping robots quietly let you down. They do the middle of the room well and leave a grey line around the outside. That line hasn’t appeared in my home since the T90S arrived.
The carpet protection is the S’s other big upgrade, and it’s the feature I’d show a sceptic first. When the robot reaches a rug, it lifts the roller by 15mm and drops a physical cover over it, keeping the wet mop away from the fibres. Lots of robots lift their mops. Far fewer actually shield them. If you’ve ever found a damp stripe across a wool rug after a “smart” mopping run, you’ll know why this matters. It’s the reason I’m comfortable running full vacuum-and-mop cycles across the whole home, rather than splitting the job and protecting rugs with no-go zones in the app.
A roller mop isn’t perfect for everything. Truly baked-on spills still benefit from a second pass or a targeted clean. But for daily upkeep of kitchen, hallway and bathroom floors, it’s the best mopping I’ve had from a robot at this price.
The Omni Station
A robot vacuum is only as convenient as its dock, and this is where the T90S earns much of its premium over the standard model. As before, the dock empties the robot’s dust bin, washes the roller with hot water (up to 75°C, according to Ecovacs UK), dries it with hot air, refills the robot’s water and dispenses cleaning solution automatically.
The new additions are the unglamorous ones that make the biggest difference over weeks rather than days. The dock now rinses its own wash tray with high-pressure water and cleans its own dirty water tank. Anyone who’s owned a self-washing mop dock knows the grim moment when you lift out the tray and find a layer of grey sludge. These features exist to prevent that, and the result is a dock I check far less often than I expected. My routine has settled into topping up clean water, emptying dirty water and changing the bag when the app prompts me.
The PowerBoost feature deserves a mention too. While the roller is being washed mid-clean, the robot tops up its battery by around 10% in three minutes. It’s a clever use of downtime, and it means the T90S rarely has to stop part-way through a full-home clean to recharge for hours.
Noise
Ecovacs rates the T90S at 60dB(A) when vacuuming in standard mode and claims it’s 5dB(A) quieter than before when vacuuming and 3dB(A) quieter when emptying. In daily life the robot is easy to ignore. I’ve happily worked from home with it running in the next room, and it never felt intrusive on calls.
The exception is the auto-empty cycle. At a rated 71dB(A), it’s short but loud, a burst of whoosh that’s noticeable in a quiet home. If you plan to schedule night-time runs, bear that in mind, or set the clean to finish while you’re still up.
App and AI features
The ECOVACS HOME app is where you set up your map, name and split rooms, draw no-go zones, choose suction and water levels per room and schedule cleans. Setup was quick, and the map has been stable, so I’ve never had to redo it.
AGENT YIKO is Ecovacs’ AI layer, and it does two things. It’s a voice assistant that understands natural-language commands like “please clean the kitchen”, and it can help with setup and troubleshooting. It also plans cleans on its own, building schedules based on your home’s layout and how you use it. I came in sceptical, as I usually am when “AI” appears on a vacuum box. In practice the voice commands are a nice extra rather than something I rely on, and the habit-based planning is useful if you’d rather not build schedules yourself. If you’re happy setting your own routine in the app, you won’t miss it, but it doesn’t get in the way either.
Battery life
The 4,000mAh battery charges in about 2.5 hours, and Ecovacs claims up to 350 minutes of runtime in standard vacuum-and-mop mode. That figure is inflated by the PowerBoost top-ups during mop washes, so treat it as a best case. What matters is that in my home it has never run out of charge mid-clean, and it doesn’t keep going back to the dock.
Verdict
After five weeks, the ECOVACS DEEBOT T90S Pro Omni has done what the best home tech does: it has disappeared into my routine. I don’t think about when the floors were last mopped or whether the rugs need a proper vacuum. I empty a water tank, change a bag every so often and get on with my day.
The upgrades over the T90 Pro Omni are sensible rather than flashy. Extra suction makes a real difference on carpets and rugs. The physical mop cover fixes one of the most annoying problems with mixed-floor mopping. The self-cleaning dock improvements cut down on the maintenance that wears most robot owners out in the long run. Together, they make a robot you can trust to get on with things.
It isn’t flawless. The black finish shows dust embarrassingly fast, the side brush can still nudge tiny objects around, and the auto-empty is loud. None of those would stop me recommending it.
Buy it if you have mixed flooring with rugs, a shedding pet or long hair in the house, or you want the most hands-off roller-mop robot you can get for under £750. Skip it if your home is almost entirely hard floor with no pets. In that case the standard T90 Pro Omni at £529 gives you very similar mopping and saves you nearly £200.
Also consider
ECOVACS DEEBOT T90 Pro Omni (£529): The predecessor shares the same 27cm OZMO Roller 3.0 and TruEdge edge cleaning, with 30,000Pa suction. It doesn’t have the mop cover or the extra dock self-cleaning. Choose it for a mostly hard-floored home on a tighter budget.
Dreame Aqua10 Ultra Roller Complete (£1,299 RRP): Dreame’s roller-mop flagship can climb taller obstacles and has a more premium dock, and it’s often discounted well below RRP. Choose it if your home has big thresholds or steps between rooms and you can find it on offer.
ECOVACS DEEBOT X12 OmniCyclone (£1,249 RRP): Ecovacs’ own flagship adds FocusJet stain pre-treatment and a bagless cyclone dock, but has lower claimed suction (22,000Pa). Choose it if you’d rather not buy dust bags and your floors see a lot of sticky kitchen spills.
