- dToF laser
- Mopping
- Roller mop
- Runtime
- About 1,277 sq ft
The best choice here for mostly hard floor homes that care about mopping and want no dust bags, since its roller mop earned the top combined mopping score in Vacuum Wars testing. It is taller than the others at 3.9 in and reviewers disagree on its obstacle avoidance. Check the street price, because it often sells far below the $1,499.99 store 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 X12 OmniCyclone
- Vacuum Wars (3.78/5): Called it the best Ecovacs robot it has tested: 100% flattened pet hair, 0% hair wrap, 23 of 24 obstacles avoided and a combined mopping score of 27.4 against a 20.3 average; carpet deep cleaning was average at 76% and crevice pickup below average. Source
- TechReviewer (8.3/10): Mopping cleaned tile, vinyl and laminate in two to three passes with strong edges; obstacle detection fell short of flagship level and the AI assistant felt unfinished; 84 minutes for a 75 m² apartment. Source
- Gizmodo: Strong mopping and a quiet dock, but the AI Agent mode got stuck and skipped areas, it hit furniture hard and struggled with cables and small objects; reviewer said it is not worth $1,500. 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
