What reviewers found
SwitchBot K20+ Pro
- PCWorld: Tested the $748.98 Patrol Kit with a required $119.99 Hub 3: the 3K camera pans 360 degrees, but with the mobile base fitted it would not cross a slightly sloped hardwood to tile transition, and it called the vacuum decent but not a main cleaner. Source
- MacSources (80%): Rated it 80% GOOD (Design 90%, Ease of Use 80%, Price 70%); praised the modular design and under furniture reach, but noted a complex app, navigation recovery issues and camera lag. Fan accessory ran 13 to 49 hours depending on speed. 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
