The S10 is for people who want a robot that fills and drains its own water from a nearby sink or laundry line, and testers rated its roller mop highly. Navigation and object detection are weak, it is tall and wide, and setup takes more work than a normal dock. At full price it is expensive, so wait for a sale or look at the newer S20.

- 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 S10
- Android Authority (AA Recommended): Three weeks of daily vacuuming and mopping three times a week ran hands off when plumbed in. The bot was about an inch too wide for the tester's chair legs and about half an inch too tall for some cabinets. Source
- The Hook Up: Called it the second best mopping performance the reviewer had measured, behind the Eufy S1 Pro, but noted weak object detection and navigation and a mop roller that does not lift high enough for high pile carpet. 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
