As shown in fig. 1, 2 and 3, an exemplary embodiment of the present disclosure provides a soil solution recovery device 100 that can be used in various types of wet surface cleaning equipment, such as an upright scrubber, a self-moving scrubber robot, etc. This foul solution recovery unit 100 can avoid the manual stubborn spot on the container internal face that washs of operator, promotes operator's use and experiences.

The dirty liquid recovery apparatus 100 is an assembly including: the recycling bin 10, the input pipe 20, the cover assembly 30, the guide wall 40, the liquid supply channel 50 and the liquid sprayer 60.

The recovery tank 10 has a bottom end 11 and a top end 12 opposite the bottom end 11. The recovery bucket 10 comprises a bottom wall 13 at the bottom end 11 and a side wall 14 extending from the bottom wall 13 towards the top end 12. The interior of the recovery tub 10 forms a recovery chamber 15.

The inlet pipe 20 is a hollow riser pipe, and external dirty liquid and debris can flow into the recovery chamber 15 through the inlet pipe 20. The lower port portion 21 of the inlet conduit 20 is located on one side of the bottom wall 13 and is capable of being in fluid communication with other components of the wet surface cleaning apparatus, such as a conduit communicating with the suction opening; the upper end opening 22 of the inlet pipe 20 extends into the recovery chamber 15. In this case, the majority of the input duct 20 is located outside the recovery chamber 15 and the input duct 20 is integral with the side wall 14; in other embodiments, the inlet pipe may also be arranged in the recovery compartment, i.e. extending from the middle of the bottom wall towards the upper top end. The bottom wall 13 defines a lower boundary of the recovery chamber 15, and the deflector wall 40 is located within the recovery chamber 15 and defines an upper boundary of the recovery chamber 15.

A lid assembly 30 is located at the top end 12 and removably sealingly covers the upper opening of the side wall 14. The lid assembly 30 includes a lid housing 31, and the lid housing 31 is detachably provided to cover the upper opening of the side wall 14.
