During operation, an operator holds the handle 101, pushes the floor washer to move forwards on the surface to be cleaned through the handle 101 or pulls the floor washer to move backwards on the surface to be cleaned, and the rolling brush motor drives the rolling brush 200 to rotate so that the rolling brush 200 wipes the surface to be cleaned. At the same time, suction force generated by the negative pressure source 103 acts on the dust collection port to suck dirt generated by wiping into the recovery container 105. When it is necessary to perform wet wiping, that is, a floor cleaning operation, a water spray switch on the handle 101 is turned on, and a pump is started to pump the cleaning liquid in the cleaning liquid container 102 to a dust suction port, and spray the cleaning liquid onto the surface to be cleaned or the rolling brush 200, so that the floor cleaning operation is performed, and dirt such as sewage generated in the floor cleaning operation is sucked into the recovery container 102.

Referring to fig. 3-10, the roller brush 200 includes a spindle 220, a wiping portion 210 and a self-driven traction wheel 230.

The wiping part 210 surrounds and is fixed to the spindle 220, and the wiping part 210 is used for wiping the floor. Alternatively, the wiping portion 210 is a wipe, which may be adhesively secured to the surface of the mandrel 220. The construction of the wiping part 210, and the combination of the wiping part 210 and the spindle 220 may also be implemented using existing household floor scrubber roller brushes, which are not limited by the present utility model.

The self-driven traction wheel 30 surrounds and is fixed on the mandrel 220, and the outer edge of the self-driven traction wheel 30 is provided with a plurality of radial protruding parts 231, and the radial protruding parts 231 are distributed along the circumference, preferably evenly distributed along the circumference.

The present embodiment is not particularly limited as to the height of the radial protrusion 231 beyond the wiping portion 210. This excess height is associated with the deformability of the radial projections 231, which may be correspondingly greater when the deformability is greater and correspondingly smaller when the deformability is less. The radial protrusion 231 may be deformed by an external force, and may be equal to or lower than the wiping part 210.
