What reviewers found
Dreame L40s Ultra
- Vacuum Wars (3.51 Vacuum Wars stars): 92% carpet sand removal, 91% pet hair pickup and 0% hair wrap with the DuoBrush, about 1,935 sq ft per charge, but only 7 of 24 obstacles avoided. Source
- Vacuum Chef (95/100): Scored 95/100 in its real world cleaning tests, measured 490 FPM carpet airflow and 78 dB at max suction. Obstacle avoidance varied by floor and object. Source
eufy Auto-Empty C10
- Vacuum Wars (2.17 Vacuum Wars stars): Measured 0.73 kPa sealed suction and 11 CFM airflow, both below average, but removed 86% of embedded sand and 100% of flattened pet hair. 37% long hair wrap, 58 min floor runtime and about 904 sq ft per charge. Ranked #3 on its under $300 list. Source
- Ideal Home: Two weeks in a family home. Easy to use and slim enough for sofas, but it bumped chair legs, climbed toys, often got stuck and missed an upstairs room when mapping. Bag was under half full after a week. Best for light maintenance cleaning. Source
