The main unit 100 includes a housing 110 and a blower assembly 120, the blower assembly 120 being disposed in the housing 110, the blower assembly 120 being communicable with the floor brush 200 and creating a suction force such that dust or debris on a surface to be cleaned can be sucked from the floor brush 200.

The floor brush 200 may have a wet mopping function, which may be performed by wetting the surface to be cleaned or wetting cleaning members, such as a drum, a mop, etc., on the floor brush 200. The suction force created by the blower assembly 120 may draw in the sewage generated by the floor brush 200 during wet mopping.

In some embodiments, the housing 110 includes a fan housing 111, the fan assembly 120 includes a fan 121 and a sound-proof shroud 122, the fan 121 is disposed in an inner cavity of the fan housing 111, the sound-proof shroud 122 is disposed between a circumferential outer side of the fan 121 and the fan housing 111, and divides the inner cavity into a first air outlet cavity 112 accommodating the fan 121 and a second air outlet cavity 113 located outside the sound-proof shroud 122, and the first air outlet cavity 112 and the second air outlet cavity 113 communicate.
