A strong value for mostly hard floor homes that want a mop washing dock without paying flagship prices. Testers liked the mopping and mapping but saw it eat cables and miss hair on carpet. Skip it if your floors are cluttered or you have long haired pets on carpet.

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
Roborock Qrevo 2 Pro
- Tom's Guide: Picked up 92.5% of cereal and 60% of hair on hardwood, but only 76.5% of cereal, 51% of flaxseed and 48% of hair on carpet. Mopping cleared soy sauce, mayonnaise and mud in two passes. It bumped furniture with some force. Source
- TechRadar: About 60 dB on carpet and 69 dB peak when emptying. Mopping was excellent on max settings, it avoided a shoe and sock but got caught on a USB cable. Subscores: Value 5/5, Design 4/5, Performance 4.5/5, App 5/5. Source
- Gizmodo (3.5/5): Cleaned a 750 sq ft apartment in just under two hours with over 50% battery left. It swept up micro USB cables and a child's sock, and the test unit needed a fix for a loose part under the brush. 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
