Further, the sewage box 34 is a box-like structure with an upper opening, and is disposed below the bottom wall of the dust collection box 33. So that the sewage can flow into the sewage box 34 through the filter screen 35.

Further, a water outlet (not shown) is provided on the sewage box 34. The water outlet of the sewage box 34 is connected with the water inlet of the first water pump 50 through a pipeline.

As shown in fig. 1, 4 and 5, the dust collection box 33 includes a box body 331 and a box cover 332 covering the box body 331, the box cover 332 is made of transparent material, and the box cover 332 protrudes from the outer surface of the housing 31 or is flush with the outer surface of the housing 31.

As can be seen in fig. 1, a user can observe the solid dirt accumulation in the case 331 from the case cover 332. When more solid dirt exists in the box 331, the box can be cleaned.

Preferably, in the technical solution of the present embodiment, the case 331 is detachably disposed on the housing 31. When the solid dirt in the box 331 needs to be cleaned, the box 331 is detached from the housing 31, and can be poured. After cleaning, the box 331 is then mounted on the housing 31, so that the floor scrubber can be used continuously.

In this embodiment, the cover 332 may be provided to be openable and closable on the case 331. When the solid dirt in the box 331 needs to be cleaned, the box cover 332 can be directly opened to directly clean the box 331. I.e. without having to disassemble the case 331.
