Abstract
The present invention provides a floor cleaner and a water sink structure thereof. In the present invention, a water sink is formed on a surface of a cleaning cylinder by a rotating roller, and a conventional water sink structure formed by a shell water sink and a filter screen is not required, so that the structure is simpler. Since a water outlet conduit and a water pumping conduit are arranged vertically to the surface of the cleaning cylinder, water is discharged and pumped on a surface of an outer sponge layer, the water supply and water pumping systems will not be blocked, and the water discharge effect and the water pumping effect are better.
