Pros
- LiDAR mapping with room-by-room control for about $250
- Covered over 1,500 sq ft per charge in Vacuum Wars’ test
- Vacuums and mops in one pass from a combined bin and tank
Cons
- Lifted just 12% of pet hair from carpet in Vacuum Wars’ test
- Some long hair wrapped on its brushes in testing
- Charging dock only: you empty the bin and rinse the mop pad yourself
- No obstacle avoidance, so cables and socks need picking up first
