## 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](https://androidauthority.com/switchbot-s10-review-3465509)
- 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](https://www.thesmarthomehookup.com/products/switchbot-s10/)

### 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](https://www.techradar.com/home/robot-vacuums/switchbot-s20-review)
- 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](https://www.expertreviews.co.uk/home-garden/vacuums-cleaning/switchbot-s20-robot-vacuum-review)
- 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](https://homekitnews.com/2025/09/28/switchbot-floor-cleaning-robot-s20-w-matter-review/)
