- Suction
- 36,000 Pa
- Navigation
- RetractSense
- Mopping
- Yes
The strongest all rounder in this group by published lab results, with 93% sand removal from carpet, no hair wrap and the best coverage per charge here. Vacuum Wars called it its favorite Roborock yet. It is new, so long term owner feedback is thin, and the small bin and weaker obstacle avoidance than Dreame's best are the main trade offs.

- Runtime
- About 200 min
A strong pick for mixed carpet and hard floor homes with low furniture and tall door thresholds, since it is under 3.2 in tall and climbs higher steps than any robot Vacuum Wars has tested. Reviewers rate its suction and edge cleaning highly but split on mopping, and Tom's Guide found the pads streaky. If spotless mopping is your main goal, a roller mop model may suit you better.
