The single cleaning operation time of the cleaning vehicle is greatly improved, the time for adding water and discharging sewage on the return journey of the cleaning vehicle is reduced, and the cost of purchasing and using the cleaning vehicle within a unit operating area is reduced. The ceramic membrane filter is mainly based on the cross-flow filtration principle of the ceramic membrane. The ceramic tube is densely covered with capillary pores. When filtering, some impurities and part of the clean water with a diameter smaller than the capillary pore diameter can pass through the capillary pores, and most of the remaining impurities are absorbed by the high-speed water flow. Flushing out of the ceramic membrane filter can prevent impurities flowing through the ceramic membrane from adhering to the surface of the ceramic membrane, maintaining a good filtration effect for a long time, high filtration efficiency, and low maintenance costs.

When there are many garbage attached to the filter, the water pump will not suck enough water. Negative pressure is generated in the pipeline, and when the pressure switch in the pipeline detects the set negative pressure signal, the feedback signal starts the vibrating pump to shake off the garbage attached to the filter net, so that the filter net always maintains a good filtering state.
