One of the better all round Roborocks for carpet and pet hair, and the slim body reaches under low furniture. The trade offs are a low 20 mm threshold limit and below average obstacle avoidance. Skip it if your home has tall thresholds or lots of floor clutter.

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 Edge 2
- Vacuum Wars (3.67 Vacuum Wars stars): 94% carpet deep clean, 89.5% pet hair pickup and 0% hair wrap, with a 40.8 combined mopping score. It avoided 14 of 24 obstacles and covered about 1,208 sq ft per charge. Source
- PCWorld: Measured 63 dB in balanced mode. Edge and corner cleaning was good, but it failed a threshold just over 0.8 in and needed several passes for dried stains. 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
