Both stations are substantial — expect to give up a decent chunk of floor space. The Roborock's dock is taller and sleeker; the Ecovacs station is wider but arguably easier to position. Neither requires you to manually empty, refill, or clean the robot more than once every couple of weeks.
Design & Build Quality
The Roborock S8 Pro Ultra — a refined, polished design with a dual rubber brush system
The Roborock S8 Pro Ultra has a premium, understated look — matte black finish, no sharp angles, clean lines. The dual rubber brush system (main roller + secondary rubber brush) is a significant upgrade over single-brush designs and handles long hair and carpet debris exceptionally well. The robot itself is fairly low-profile at 9.65cm, which gets it under most UK sofas.
The Ecovacs Deebot T30 Pro Omni — slightly taller but packs serious mopping power
The Ecovacs T30 Pro Omni is slightly taller at 10.2cm, which can be a problem under lower furniture, but the trade-off is a more powerful internal layout. The spinning twin mop pads are mounted on motorised arms that can extend independently, allowing the machine to mop right up to skirting boards — something the Roborock doesn't manage as effectively.
Winner: Draw. Both are premium-feeling machines. The Roborock is marginally lower-profile; the Ecovacs has a more capable mop mechanism.
Navigation & Mapping
Both robots use LiDAR-based navigation, but with notable differences in implementation.
Roborock: PreciSense LiDAR
The Roborock S8 Pro Ultra uses Roborock's PreciSense LiDAR system — one of the most mature and reliable navigation platforms in consumer robotics. In our testing across multi-room UK homes, it mapped accurately on the first pass, rarely got stuck, and handled furniture legs and irregular layouts with impressive consistency.
The accompanying Roborock app is genuinely excellent: room labelling, cleaning order customisation, no-go zones, carpet detection, and the ability to set cleaning intensity per room are all included. If you want to be hands-off, just run it. If you're a tinkerer, the app has more settings than you'll probably ever use.
Ecovacs: dToF LiDAR + AIVI 3D
The T30 Pro Omni adds AIVI 3D object recognition on top of LiDAR mapping. This means it can identify and avoid socks, cables, shoes, and pet waste in real time — a meaningful upgrade if your home tends towards organised chaos. The camera-based recognition works well in daylight, less reliably in the dark.
The Ecovacs app (ECOVACS HOME) has improved significantly in 2025/2026. It's not quite as polished as the Roborock app, but it's perfectly usable. Some users report occasional mapping resets — a known quirk of the Ecovacs platform.
Winner: Roborock for consistency and app quality. Ecovacs for object avoidance.
Suction Power
On paper, this comparison looks decisive: 11,000 Pa (Ecovacs) vs 6,000 Pa (Roborock). But suction Pa is one of the most misleading numbers in robot vacuum marketing.
In real-world cleaning, both machines perform excellently on hard floors and medium-pile carpets. The difference becomes noticeable on high-pile or thick carpets, where the Ecovacs' additional power does give it a measurable edge at removing embedded debris.
For most UK homes (with a mix of hard floors, rugs, and standard carpets), either machine will clean to a standard that rivals a manual vacuum — though neither replaces a deep periodic clean on heavily soiled carpets.
Winner: Ecovacs on carpet suction, especially thick pile. Draw on hard floors and standard carpets.
Mopping Performance
This is where the comparison gets interesting.
Roborock: VibraRise 2.0 (Sonic Vibration)
The Roborock uses a single mop pad with sonic vibration — it oscillates rapidly to scrub floors. It lifts the mop 5mm when it detects carpet, preventing soaking. Performance on everyday dirt, spills, and foot traffic marks is excellent. For light-to-medium mopping jobs, you'll be genuinely impressed.
Where it falls slightly short is on stubborn stains and dried spills — the single pad doesn't generate quite the same mechanical scrubbing action as spinning pads.
Ecovacs: OZMO Turbo 2.0 (Dual Spinning Pads)
The T30 Pro Omni uses two spinning mop pads that rotate at 180 RPM while pressing down with 1N of pressure each. For hard floors that need a proper scrub, this is noticeably more effective. The spinning pads can also be hot-washed in the dock, which means fresher cleaning over multiple runs.
The mop pads lift 15mm when carpet is detected — significantly higher than the Roborock's 5mm, which matters if you have plush or thick-pile carpet that the Roborock's lifted pad still grazes.
Winner: Ecovacs — convincingly better mopping, especially on tile, wood, and kitchen floors.

Dock & Maintenance
Both docking stations handle:
Auto-empty: Vacuums debris from the robot's dustbin into a sealed bag
Mop washing: Rinses the mop pads with clean water
Mop drying: Warm air drying to prevent mildew
Water refill: Tops up the robot's clean water tank
The Roborock RockDock Ultra — tall, clean, and fully automated
The Roborock dock uses hot air drying and a self-cleaning mop wash cycle that consistently leaves pads fresh. The clean/dirty water tanks are easy to access and refill.
The Ecovacs OMNI Station — wide but functional, with hot air mop drying
The Ecovacs dock hot-washes the spinning mop pads at 55°C, which is a meaningful hygiene advantage. The auto-empty system uses disposable bags (included; replacements are inexpensive). Some users report that the Ecovacs dock's dirty water tank fills slightly faster due to the more aggressive mop washing.
Winner: Draw. Both are exceptional docking stations. Ecovacs' hot-wash mop drying is slightly more hygienically thorough; Roborock's station is marginally more compact.
Noise Levels
Neither machine is silent, but both are reasonable.
Roborock S8 Pro Ultra: ~68 dB at max suction, ~57 dB at quiet mode
Ecovacs T30 Pro Omni: ~72 dB at max suction, ~59 dB at quiet mode
Both offer quiet/silent modes suitable for running overnight or during the work day. The dock emptying cycle is loud on both (comparable to a hairdryer) and lasts 20–30 seconds — schedule this to avoid early mornings if you have sleeping children nearby.
Winner: Roborock — marginally quieter across all modes.
App & Smart Home Integration
Roborock App
The Roborock app is widely considered the gold standard in robot vacuum apps. Features include:
Multi-floor mapping with room labelling

How They Compare to Other Options
If you're still on the fence, it's worth knowing where these machines sit in the broader market:
Dreame X50 Ultra — the most advanced robot vacuum currently available in the UK, with obstacle-climbing and the most sophisticated AI navigation. Pricier, but worth considering if budget allows. See our full guide to the best robot vacuums UK 2026.
Roborock Q7 Max+ — a step down from the S8 Pro Ultra with slightly less mopping capability, but cheaper. Good middle ground. Read the Roborock Q7 Max+ review.
iRobot Roomba j7 — strong on navigation and obstacle avoidance, but no mopping. A solid choice if mopping isn't a priority. See our Roomba j7 review.
Which robot vacuum is better for pet hair: Roborock S8 Pro Ultra or Ecovacs T30 Pro Omni?
Both handle pet hair well, but for different reasons. The Roborock's dual rubber brush system is less prone to tangling with long pet hair, making maintenance easier. The Ecovacs' AIVI 3D object avoidance is better at detecting and avoiding pet "accidents" on the floor. For a home with multiple shedding pets, we'd lean toward the Ecovacs for avoidance and suction power.
Can both robots mop and vacuum at the same time?
Yes — both the Roborock S8 Pro Ultra and Ecovacs T30 Pro Omni can vacuum and mop simultaneously. Both also automatically lift their mop pads when they detect carpet to avoid soaking your rugs, though the Ecovacs lifts higher (15mm vs 5mm).
How often do you need to refill the water tanks?
With the fully automated docking stations, both machines refill themselves after each cleaning cycle from the dock's clean water tank. You'll typically need to refill the dock's clean water tank every 2–4 sessions depending on how much mopping is done. This is typically once or twice a week for a medium-sized home.
Are these robot vacuums worth the price for a UK home?
For a home where you'd otherwise vacuum 3–5 times per week, a premium robot vacuum like these pays for itself in time saved within months. Both machines can genuinely replace daily vacuuming in most homes. The mop function reduces (though doesn't eliminate) the need for manual mopping. At £750–£1,000, they're a serious investment, but one that delivers real daily utility.
Can these robots handle stairs or multiple floors?
No robot vacuum handles stairs — they all stop at the edge. Both the Roborock and Ecovacs can map and clean multiple floors (with separate maps), but you'll need to carry the robot to each floor. The automated dock only works on the floor where it's installed.
Final Verdict
Both the Roborock S8 Pro Ultra and the Ecovacs Deebot T30 Pro Omni are exceptional robot vacuums that will genuinely transform your daily cleaning routine. Choosing between them comes down to your floor type and priorities.
Roborock S8 Pro Ultra: The safer, more consistent choice for mixed-floor UK homes. Excellent navigation, a superior app, and a mature platform you can trust. It's the best all-rounder in this price bracket.
Ecovacs Deebot T30 Pro Omni: The better choice for homes with predominantly hard floors, pet owners who need obstacle avoidance, and anyone who wants genuinely impressive mopping without spending more. The lower price point sweetens the deal.
For most UK households, we'd give the slight edge to the Roborock S8 Pro Ultra for its consistency and ease of use — but you genuinely can't go wrong with either.
