Roborock Qrevo CurvX vs Ecovacs Deebot T80 Omni: spinning pads or a self-rinsing roller mop?

The Roborock Qrevo CurvX and the ECOVACS DEEBOT T80 OMNI are both premium all-in-one robots. Each vacuums, mops, empties itself into a dock, and washes and dries its own mop. On paper they look similar. In practice they take different approaches to the job that matters most for many hard-floor homes: mopping.

This comparison is based on the makers' published specifications and our buying checklists. We haven't run these robots ourselves. The spec table above covers the basics, so below we focus on the differences that should drive your decision.

Mop type: spinning pads vs a self-rinsing roller

This is the biggest difference between the two.

Roborock Qrevo CurvX uses dual spinning mops rated up to 200 RPM and 12 N of pressure. The mop and side brush extend outward to reach edges, and the mops lift up to 17 mm when the robot meets a rug.

ECOVACS DEEBOT T80 OMNI uses the OZMO ROLLER, a roller mop that rinses itself with clean water while it scrubs. ECOVACS rates it at up to 200 rpm and 3,700 Pa of pressure. The catch is the lift: the roller rises only 10 mm, so deep-pile rugs are best set as no-mop zones.

What this means for you:

• If you mop a lot of kitchen and dining floor and want results closer to a manual mop, the T80's self-rinsing roller is its main selling point.
• If your home mixes hard floors with rugs, the CurvX's higher mop lift gives more clearance. You'll spend less time drawing no-mop zones.

Dock features: hot-water wash, drying and emptying

Both docks wash the mop with hot water and dry it with 45°C hot air. The details differ:

• Wash temperature: The CurvX lists an 80°C hot-water wash. The T80 OMNI lists a 40–75°C range.
• Water tanks: ECOVACS publishes a 4 L clean / 2.2 L dirty water setup for the T80 station. Roborock's page doesn't list tank sizes for the CurvX.
• Dust emptying: Roborock rates the CurvX for up to 65 days of hands-free emptying. The T80 OMNI's station uses 3 L dust bags that need replacing. If you'd rather not buy bags, note that ECOVACS lists the T80 as a bagged dock.
• Dock size: The CurvX dock measures 450 × 450 × 450 mm, which takes real floor space. ECOVACS doesn't list station dimensions in our facts, so measure your spot against the store page before buying either.

Navigation and obstacle avoidance

Both pair a laser-based distance sensor with a camera system for spotting obstacles.

• Roborock Qrevo CurvX: RetractSense retractable LiDAR, plus structured light and an RGB camera. Roborock says the system recognizes 108 object types. The LiDAR drops down so the robot can fit under low furniture.
• ECOVACS DEEBOT T80 OMNI: dToF navigation with AIVI 3D 3.0 (RGB plus structured light) for obstacle avoidance.

On paper, both are well equipped to avoid cords, socks and pet mess. The CurvX's distinctive feature is the retracting sensor, which is about height as much as navigation.

Height and getting around the home

• CurvX: 79.8 mm tall with the LiDAR retracted.
• T80 OMNI: 98 mm tall, which is still slim for a robot with a full station.

That roughly 18 mm gap can decide whether a robot reaches under a low sofa or bed frame. Measure the clearance under your lowest furniture before choosing.

The CurvX also lists AdaptiLift threshold climbing up to 4 cm, useful in older homes with raised door sills. ECOVACS rates the T80 for obstacles up to 20 mm.

Two more spec points matter here:

• Suction: The CurvX is rated up to 22,000 Pa and the T80 OMNI up to 18,000 Pa.
• Runtime: ECOVACS publishes runtime and battery figures for the T80: up to 223 minutes of standard vacuuming on hard floors from a 6,400 mAh battery. Roborock doesn't publish runtime or battery capacity for the CurvX.

ECOVACS's page also doesn't state the T80's warranty length, so check the store listing for coverage. For more robot options, see our best robot vacuums roundup.

Who should buy the Roborock Qrevo CurvX

• Homes with low sofas and beds, where the 79.8 mm height and retractable LiDAR matter
• Pet owners with long-haired pets (see also our best vacuums for pet hair)
• Mostly hard-floor homes with some rugs and thresholds, thanks to the 17 mm mop lift and 4 cm threshold climbing
• People who want the highest rated suction of the pair
• Skip it if you have no room for a 450 mm-cube dock, or you only need basic vacuuming without mopping

Who should buy the ECOVACS DEEBOT T80 OMNI

• Homes with lots of tile or wood
• Families with kitchens and dining areas that get sticky
• Anyone who wants mopping that rivals a manual mop, via the self-rinsing roller
• Buyers who want published runtime figures (up to 223 minutes on hard floors) and a large 4 L clean-water tank
• Skip it if your home is mostly thick carpet, or you want a bagless dock

FAQ

Is a roller mop better than spinning pads?

For heavy mopping, the T80 OMNI's roller has an edge on paper because it rinses itself with clean water as it scrubs, so it isn't spreading dirty water around. Spinning pads like the CurvX's lift higher over rugs (17 mm vs 10 mm) and extend outward for edges. Which is "better" depends on whether your floors are mostly hard surfaces or a mix with rugs.

Which robot fits under lower furniture?

The Roborock Qrevo CurvX. It's 79.8 mm tall with its LiDAR retracted, versus 98 mm for the DEEBOT T80 OMNI. Measure the gap under your lowest sofa or bed before you buy.

Do I need to buy dust bags?

For the T80 OMNI, yes. Its station uses 3 L dust bags that need replacing. Roborock rates the CurvX for up to 65 days of hands-free emptying, but check the store page for its consumables before buying. For more gift ideas, see our gifts for new homeowners list.
