The water delivery pump 56 and the negative pressure generating structure 57 are started, the second valve 531 is opened, the water filtered by the water delivery pump 56 in the filtering device 40 is pumped into the water outlet device 20 and discharged from the outlet 201 of the water outlet device, the discharged water forms a water curtain on the inclined plane 11 for people to clean the soles, and the sewage after cleaning the soles enters the sewage tank 30. The negative pressure generating structure 57 draws air from the filtering apparatus 40 so that a negative pressure is formed inside the filtering apparatus 40, and the sewage in the sewage tank 30 is sucked into the filtering apparatus 40 by the negative pressure. The water pump 56 and the negative pressure generating structure 57 are continuously operated so that the water in the shoe sole washing machine can be circulated.

In another preferred embodiment, the top of the filtering device 40 is further provided with a water replenishing port, through which water can be replenished when the water of the whole sole washing machine is lost, such as periodically replenishing water according to working time.
