What reviewers found
Dreame L10s Ultra Gen 2
- Tom's Guide: Scored 85% overall pickup: Cheerios 80% on hardwood and 90% on carpet, kitty litter 95% on both, pet hair 70% on hardwood and 80% on carpet. Bumped into walls and large objects and CleanGenius mistook wood grain for stains. Source
- Stuff (South Africa) (8.5/10): Reliable LiDAR navigation and low maintenance, never needed a mid clean recharge in a small flat. Tomato sauce stains needed extra passes and the top knob blocked low furniture. Subscores Design 8, Performance 9, Features 9, Value 8. 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
