The first sewage recovery system is mainly an intermittent operation mode (certainly working all the time) of sucking redundant water stains into sponge like the existing sponge mop, sucking the water in the sponge to a certain degree, pumping out the sewage in the sponge through the water sucking hole 82 by the miniature water pump 84 through the water sucking pipe 83 and pressing the sewage into the sewage tank 63, and the miniature water pump 84 can be designed to work again after a period of time delay after the disc brush 1 or the rolling brush 14 is started to work, stop the work for a while and work again for a while.

The sponge strip 81 is generally PVA glue cotton used for mopping, and can be made of other soft water-absorbing materials (such as wood pulp cotton, PU, PP, PVC sponge, etc.), preferably, wear-resistant and corrosion-resistant materials are also added, and ultra-fine fiber cloth with better water-absorbing performance can be attached to the bottom of the sponge (the place attached to the cleaning surface) (or the sponge strip is wrapped by the ultra-fine fiber cloth).

The suction pipe 83 and the suction port 82 are not necessarily wrapped in the sponge strip 81, and may be supported on the top, front side or rear side of the sponge strip by a support, so that the sponge strip can be easily replaced, but the water pipe needs a support and has poor aesthetic property, and the upper side of the sponge strip 81 supports the suction pipe 83 and the suction port 82 from the lower side.

When the water washing cleaning apparatus includes the rolling brush 14, the first sewage recovery system may be further provided on the chassis 10 of the water washing cleaning apparatus, as shown in fig. 8 and 9, which is provided at the rear of the chassis 10 (the moving direction of the water washing cleaning apparatus is forward), when the suction port 2 is located at the rear side of the rolling brush 14 (the moving direction of the water washing cleaning apparatus is forward), the first sewage recovery system is located at the rear side of the suction port 2, when the suction port 2 is located at the left side or the right side of the rolling brush 14, the first sewage recovery system is located at the rear side of the rolling brush 14, and the sponge strip 81 is held by the holding member 87 on the chassis 10.

The clean water tank and the waste water tank of the water washing and cleaning apparatus may be located on the chassis 10 as shown in fig. 1 and 3, or on other support mechanisms, wherein the cleaning portion may be connected to the support mechanism where the clean water tank and the waste water tank of the water washing and cleaning apparatus are located by a hand-held lever, wherein the water washing and cleaning mechanism is partially shown in fig. 12 and 13, and the clean water pipe 53 and the water pump output pipe 852 are connected to the clean water tank 51 and the waste water tank 63 through the hand-held lever.

The sponge strip 81 is clamped by the clamping component 87, the shape of the sponge strip 81 is changed along with the shape change of the clamping component 87, the sponge strip 81 can be arranged into a linear strip through the clamping component 87, the sponge strip 81 is not necessarily arranged into a linear strip, and can also be arranged into an arc strip, and the strip surrounds the periphery of the disc brush 1 or the chassis 10 or the rolling brush 14 of the water washing cleaning device, or is a V-shaped strip or a trapezoid (the bottom edge is lacked, and the opening faces the disc brush 1 or the chassis 10 or the rolling brush 14). The manner of adding the sponge strips 81 on the outer side of the water washing cleaning device can compensate the cleaning effect of the disc brush 1 or the rolling brush 14 on the top corner and the wall corner (concave part) of the glass window to a certain extent. The cross section of the sponge strip can be in various shapes, such as rectangle, square, parallelogram and the like, and can also be rounded.

The invention is suitable for hand-held mopping machines with mopping function, and is also suitable for cleaning robots, or for machines which automatically clean facades (robots) or hand-held facades (such as outer walls or glass) by washing with water.
