The screw mechanism 28 drives the spray assembly to reciprocate, and the cleaning is more comprehensive. The waste water in the upper frame 6 enters the lower frame 3 through the drain pipe, and then flows back to the water tank 33 through the arc groove 37 in the lower frame 3. The filter net 36 filters the return water to facilitate the recycling of water.
