- Suction
- iRobot claims 70x
- Navigation
- ClearView LiDAR
- Mopping
- Reusable microfiber pad
A space saving Roomba with no tall dock, good LiDAR navigation and a large compacting bin. TechRadar needed to empty it after 8 days rather than 60 and measured 78 dB. Mopping and obstacle handling are weak, so it suits small tidy homes.

One of the best carpet and pet hair cleaners at its price. Vacuum Wars measured 96% sand and 96% pet hair pickup with no hair wrap. It avoided only 6 of 24 obstacles and the dock does not wash mops, so it suits tidy homes with mostly carpet.
