What reviewers found
iRobot Roomba 105 Vac + AutoEmpty Dock
- Vacuum Wars (1.41 Vacuum Wars stars): Removed 82% of embedded sand, above the 75% average, but picked up only 29% of flattened pet hair and 79% of long hair wrapped the brush. Coverage was about 630 sq ft per charge and it has no obstacle avoidance. Source
- RTINGS: Named the Roomba 105 its best cheap robot vacuum for smart navigation, long battery life and an optional self empty dock, but called vacuuming only adequate and obstacle avoidance weak. Source
MOVA E40 Ultra
- Vacuum Wars (2.92 Vacuum Wars stars): Bought and tested in house against the original P10 Pro Ultra: 88% carpet deep clean against a 77% average, but 47% flattened pet hair pickup, 44% hair tangle, 5 of 24 obstacles avoided and about 1,602 sq ft per charge. Source
- Gizchina.it: Used for several weeks as the main home robot: mapping was quick and accurate, the app stable. In turbo mode on about 60 m2 it could drop to about 20% battery, then it recharges and resumes. Suction on long pile carpet may disappoint. Source
