What reviewers found
eufy Omni C20
- Vacuum Wars (2.21 Vacuum Wars stars): Removed 96% of flattened pet hair and 75% of embedded sand, scored 227 on mopping against a 171 average, but 54% of long hair wrapped the brush and it covered only about 525 sq ft per charge. The page header shows 2.21 stars while its verdict text cites 3.09. Source
- RTINGS: Great on bare floors and along walls, only okay on carpet and passable on pet hair. Struggled with power cords and gave weak stain removal because the robot has no water tank of its own. Source
Roborock QV 35S
- Tom's Guide: On hardwood it picked up 92% hair, 94.5% puffed rice and 98% flax seeds. On high pile carpet it got 40% hair and 38.5% flax seeds. About 55 dB mopping and 60 dB vacuuming. Called it ideal for hardwood homes. Source
- Ideal Home: Handled rice, flour, ketchup and dog hair on hard floors, mapped each floor in about 5 min, and had about 40% battery left after the whole house. Weaker on carpet and dog hair in rugs, and the app was buggy at times. Source
