The scraper 842 can contact the circumferential surface of the filter element 820 when the filter element 820 rotates, and impurities which can be positioned on the filter element 820 are extruded out of the filter element 820, so that the filter element 820 is prevented from being blocked by impurities, and the filtering effect of the filter element 820 can be ensured.

The working principle of the preferred embodiment of the present invention is briefly described below. The wiping and sweeping robot 1000 is started by the power supply unit of the wiping and sweeping robot 1000, and after the starting, the central control processing unit controls the driving device, the side sweeping assembly 210, the middle sweeping assembly 300 and the floor wiping assembly 400 to work. When the floor scrubbing assembly 400 is in operation, the sprinkler assembly 930 begins to spray onto the floor scrubbing assembly 400. When the water on the floor wiping assembly 400 is recovered by the water return assembly 900, the water flows into the water filtering device 800 through the water return assembly 900. Because the driving device is operated, the rotating shaft 821 rotates, the magnetic coupling wheel 822 rotates, the filter element 820 is driven by the driving device to rotate continuously, and the water recovered by the water return assembly 900 passes through the upper filter plate 830 for one-time filtration, so that some larger impurities in the water can be filtered simply. Water enters the filter base 810 from the upper filter plate 830, and water after once filtration by the upper filter plate 830 enters the filter base 810 from the water inlet 813. Because the abutment surface 811 is in close contact with the filter element 820, water enters the filter element 820 in the radial direction from the water inlet 813 and exits the filter element 820 into the water outlet 812 under the air pressure in the negative pressure space. The "stitch-type filtration mode" and the "side filtration mode" are novel, and take a lot of research time of the inventor, and are an creative filtration mode. In addition, the needle-type filtering mode and the side filtering mode are approved by customers, and the filtering effect is very good.

Specifically, as shown in fig. 7, under the action of suction force, water enters the filter base 810 from the first water inlet direction N1, and water enters the filter base 810 from the second water inlet direction N2, and water entering the filter base 810 from both sides is filtered by the filter element 820 and is discharged from the water outlet 812 in the water discharge direction O1. On the other hand, the filter element 820 continuously rotates, and when the filter element 820 rotates to the extrusion part 840, the scraping plate 842 on the extrusion part 840 can squeeze the filter element 820, so that sundries on the filter element 820 are squeezed out of the filter element 820, and water can be squeezed out of the filter element 820 when passing through the scraping plate 842, so that the filter element 820 is prevented from being blocked by the impurities. A water suction pump for sucking water is connected to a water suction port 814 on the filter base 810.
