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
eufy Omni C28
- Vacuum Wars (3.70/5): Measured 89% carpet sand removal, 100% pet hair pickup, 0% hair wrap, 15 of 24 obstacles avoided, about 1,191 sq ft per charge and a 29 combined mopping score with 0.25 g of water left behind. Source
- Tom's Guide: Picked up 98% of Cheerios and 99% of kitty litter on hardwood, 95.5% and 98% on carpet, and 82% and 92% of pet hair; overall cleaning score 94%, with some erratic pathfinding. Source
