- Mopping
- Yes
- Runtime
- 4,000 mAh battery
The best value roller mop robot in Vacuum Wars testing, with near perfect obstacle avoidance, perfect pet hair pickup and the top mopping score in its price range. Not every reviewer agrees: TechRadar's long test in Australia found slow mapping, streaky mopping and hair tangles. Buy it at the $549 sale price, not the $799.99 list price.

- Navigation
- 3D ToF and camera
- Mopping
- Spinning pads
- Runtime
- About 200 min
A strong pick for mixed carpet and hard floor homes with low furniture and tall door thresholds, since it is under 3.2 in tall and climbs higher steps than any robot Vacuum Wars has tested. Reviewers rate its suction and edge cleaning highly but split on mopping, and Tom's Guide found the pads streaky. If spotless mopping is your main goal, a roller mop model may suit you better.

What reviewers found
Ecovacs Deebot T90 Pro Omni
- Vacuum Wars (4.00/5): Measured 21 CFM airflow, 81% carpet sand removal, 100% pet hair pickup, 0% hair wrap, 23 of 24 obstacles avoided, about 1,372 sq ft per charge and a 34.6 combined mopping score versus a 20.3 average; it cleared 32 mm against a 40 mm claim. Source
- TechRadar: Tested in Australia. Mapping took six sessions, auto mode mopped carpeted bedrooms, pet hair was left behind and tangled in the brush, and wood floors were left streaky. The reviewer did not recommend it. Source
- Notebookcheck: Very good mopping and nearly perfect medium pile carpet pickup at max suction; it touched thin chair legs and missed a small toy brick, and corner cleaning was weaker. Measured about 58 dB on carpet at standard settings. Source
Roborock Saros 20
- Vacuum Wars (3.81/5): Lab tests found 89% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap, 17 of 24 obstacles avoided, a record 57 mm threshold climb and an above average combined mopping score; battery coverage was slightly below average at about 1,038 sq ft per charge. Source
- CGMagazine (8.5/10): Performed strongly on pet hair, sand and fine dust on carpet and hard floors and fit under low furniture; reviewer flagged middling battery life, a small bin and trouble with loose cables. Source
- Tom's Guide: Picked up 100% of cereal and kitty litter on carpet and 70% of pet hair on carpet, but mopping left floors streaky and patchy and the pads fell off once crossing a cable. Source
