5 Differences Between the Xiaomi H40 and S40 Robot Vacuums

Suction power The H40 has 4000Pa of suction, while the S40 has 3000Pa. This matters if you have carpets or pets.

Mopping system The H40 has a bigger water tank and better navigation precision for mopping. The S40’s mopping is more basic.

Battery life The H40 has longer battery life. The S40’s battery is shorter but still sufficient for small apartments.

Best for carpets The H40’s higher suction makes it the better choice for homes with carpets. The S40 struggles on carpeted floors.

Best for small hard-floor apartments The S40 cleans fine on hardwood or tile in small spaces. It costs less and does everything needed for a 600-square-foot apartment.
