A good fit for hard floor homes that want a roller mop and no dust bags. BGR found mopping and pet hair pickup strong and The AU Review called it the best robot vacuum its reviewer had used. It is very new with no independent lab numbers yet, and the older X12 does much the same for about $400 less.

- 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 X12S OmniCyclone
- BGR: Picked up debris well on carpet and hard floors and mopping was strong, though some stubborn stains stayed; first map merged rooms and needed about 15 minutes of editing, and the dock full alert was easy to miss. Source
- The AU Review (5/5): Three weeks in an apartment with a shedding dog; cleaned hardwood and light rugs thoroughly in under an hour, but got stuck on a sock once. 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
