- 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.

- Laser based 3D mapping
- Mopping
- Yes
- Runtime
- 7,000 mAh battery
A well rounded flagship for homes with pets and mostly hard floors. Vacuum Wars measured strong suction, no hair wrap and good obstacle avoidance, and its retest after a firmware update rated the mopping well above average. Tom's Guide was less impressed with edges and corners, and the 3.74 in body will not fit under the lowest furniture.

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
Narwal Flow 2
- Vacuum Wars (3.88/5): Lab tests found 84% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap and 20 of 24 obstacles avoided; a retest after a firmware update put mopping well above average, but the studio vacuum and mop run lasted only 38 minutes. Source
- Tom's Guide: Picked up 100% of kitty litter on both floors, 100% of pet hair on hardwood and 80% on carpet, but only 30% and 20% of cereal; reviewer said edges and corners need manual cleaning and it does not live up to its price. Source
- 9to5Google: Cleaned about 1,300 sq ft with back to back vacuum and mop passes without stopping to recharge; reviewer rated it roughly equal to the Roborock Saros 20 but noted the taller body. Source
