During the sweeping and washing process, the small particles and small lumps of solid waste in the working area are collected into the garbage bin 7 through the relative turning of the two roller brushes. At the same time, through the friction between the bristles and the ground, the dirt on the ground is effectively removed. The sewage formed after sweeping and washing is recycled into the sewage tank 1 through the wiper rake assembly 13 and the suction fan assembly 16, so as to achieve the function of cleaning the ground.
