Roborock Qrevo Curv 2 Flow vs Ecovacs Deebot T80 Omni
By Emma Walsh
These two are the same idea from rival brands. Each mops with a roller, and each has a dock that empties the bin, washes the roller in hot water, dries it and refills the tank, and neither adds its own detergent. They sit in the same price band as well. So look at the three places the robots themselves differ: how tall they are, what they do at a carpet edge and the battery they carry.

Choose the Qrevo Curv 2 Flow if
- You have rugs or low carpet next to hard floor: its roller lifts 15 mm, as high as any robot in our list
- You'd like the bigger bin in the robot, 324 ml against 220 ml
- Nothing in your house sits lower than 12 cm off the floor
Choose the Deebot T80 Omni if
- Your couch or beds have less than 12 cm under them: it's 9.8 cm tall against 11.9 cm
- You have a big single-level house: its battery is 6,400 mAh against 5,200
- The dock has to fit a narrow spot: it's 34 cm wide, and the Roborock's is a 45 cm cube
Under the couch
The first difference is one you can check with a ruler. The Curv 2 Flow is 11.9 cm tall, which makes it the second-tallest robot in our list, and the T80 Omni is 9.8 cm. Two centimetres is the gap between cleaning under the bed and bumping along the front of it, so measure your lowest furniture before you read any further. The T80 also climbs a 2 cm sill with its mop on.
The roller, on tiles and on rugs
Both mop with a roller that slides out towards the skirting boards, and the Roborock’s gets to within about 10 mm of the edge. Both docks wash the roller in water heated up to 75°C. The pressure figures come in different units, 15 N for the Roborock and 3,700 Pa for the Ecovacs, so they can’t be ranked against each other.
At a carpet edge the Curv 2 Flow lifts its roller 15 mm, as high as any robot in our list, against 10 mm on the T80. That extra clearance is for rugs and low carpet, though, because the Roborock isn’t meant to be used on high-pile carpet at all. If there’s a shaggy rug in the lounge, this isn’t the robot for it.
Picking up
Suction is 20,000 Pa on the Roborock and 18,000 Pa on the Ecovacs, and we wouldn’t choose on a gap that small. The hardware underneath differs more. The Curv 2 Flow has two short rollers for a main brush and two side brushes that lift, where the T80 has an anti-tangle side brush that doesn’t extend. The Roborock’s bin is also half as big again, 324 ml against 220 ml, though that counts for less when both docks empty the bin for you.
Both use a front camera to spot clutter and a laser to map, so there’s nothing to separate them there.
The battery, and where the dock goes
The T80 has the bigger battery, 6,400 mAh against 5,200. It runs for up to 297 minutes in its quietest vacuum-only mode, and the Curv 2 Flow for up to 242 in quiet mode. Runtimes from different brands aren’t measured alike, so if you have a big single-level house, go by the battery. The Roborock takes about three hours to charge from 15 per cent to full.
The docks do the same jobs in different shapes. Roborock’s is a 45 cm cube. The Ecovacs dock is narrower at 34 cm, and it stands 50 cm high and 46 cm deep with its ramp, so it’s the one for a narrow gap beside the laundry bench. It holds a 3-litre dust bag, a 4-litre clean tank and a 2.2-litre dirty tank.
Every spec, side by side
Shaded rows are where the two differ. "Not stated" means the brand doesn't give that number. Each product's spec sheet shows where its figures were read.
Final thoughts
For most houses we'd take the Deebot T80 Omni. It's 2 cm lower and it carries the bigger battery, from the same price band, and those are the things that decide whether a robot reaches the whole floor.
The Qrevo Curv 2 Flow is the better fit for a home with open space, nothing low to duck under and a lot of rugs or low carpet between the hard floors. That's because its roller lifts higher. Measure under the couch first, because a gap of less than 12 cm rules the Roborock out.
