- No
Built for small apartments and rooms packed with furniture, since it is only about 25 cm across and its dock is smaller than a sheet of A4. Reviewers like the speedy cleaning and big 4 L dock bag, but treat it as a vacuum only, because the wipe mop is weak. Skip it for larger homes, cluttered floors or heavy pet hair, and wait for a sale since it often drops well below $400.

- Mopping
- RevoRoll roller mop
A good value all in one mopping robot when it is on sale, with a roller mop that testers liked and AI camera obstacle avoidance. It is loud, tall and large, and TechRadar saw docking problems, so it suits open homes more than tight ones. Skip it if you need a mop only mode or quiet runs.

What reviewers found
SwitchBot K11+
- TechRadar: Charming, capable vacuum for cramped homes with fast, accurate navigation and a large dock bag; the wipe mop is not worth using, auto empty is noisy and it hit a shoe and sucked up a cable. TechRadar gave a Performance 3.5/5 subscore but no overall rating. Source
- Tom's Guide: Picked up all kitty litter but struggled with Cheerios; mapping needed about four attempts and the reviewer preferred the cheaper K10+ Pro unless battery life or noise matter most. Source
- Expert Reviews: Near perfect rice pickup on carpet and laminate, but weaker on flour and pet hair; it ran over socks and cables and did not detect a fake dog mess. Source
SwitchBot S20
- TechRadar: Effective roller mop and strong obstacle avoidance, but louder than average in every mode, regular docking failures and some erratic navigation. Subscores: Value 3.5/5, Design 4/5, Performance 3/5, App 3.5/5. Source
- Expert Reviews: Picked up 50 of 50 g rice and 5 of 5 g pet hair on hard floor, 29.4 of 50 g flour on carpet, and removed dried mud in two passes and ketchup in three. Measured 65 dBA at 1 m. Source
- HomeKit News (8/10): Solid obstacle avoidance that was sometimes overcautious; Matter 1.4 rooms work in Apple Home, but there is no mop only option and cleaning fluid must be added by hand. Source
