Most owners praise this vacuum for its precise LiDAR mapping, quiet operation, and methodical cleaning that handles pet hair and mixed floors well. The real trade-off is a small dust bin that fills quickly, especially in homes with pets, so you’ll be emptying it often.
Loved by buyers
- •LiDAR navigation maps your home accurately and cleans in efficient rows, reaching under furniture and along edges without the chaotic bumping of older bots.
- •Quiet enough to run while working or around noise-sensitive pets, with a low whir rather than the scream of a typical upright.
- •Strong suction automatically boosts on carpet and pulls up fine dust, debris, and pet hair from hard floors, tile, and low-pile rugs.
Buyer concerns
- •Dust bin is undersized and fills up quickly, often needing a mid-clean empty in pet-heavy homes, and there’s no self-emptying base option.
- •You must enable map saving in the app’s beta settings before the first run; missing that step means you lose your map and any custom zones.
- •It’s vulnerable to cords and small objects left on the floor, so you need to tidy up before each session to avoid tangles.
