When the floor suction nozzle moves on the surface to be cleaned, whether the floor suction nozzle moves forwards or backwards, one chamber of the liquid inlet gap 17 is in an open state, and the other chamber is in a closed state, so that the effective water absorption sectional area of the liquid inlet gap 17 is reduced, and the suction force is increased, and the water absorption capacity of the liquid collecting mechanism 14 on the floor suction nozzle is improved. From knowledge of fluid dynamics, the increase in suction force here is manifested in an increase in the flow velocity of the fluid due to the smaller cross-sectional area through which the fluid passes, and thus in the water absorption efficiency. In addition, one of the two scraping lips deforms to form a narrow channel, and the other one plays a role of the scraping lips to prevent residual liquid on the ground after cleaning.
To facilitate installation of the wiper strip liner 19, the wiper strip liner 19 is configured to be removably mounted to the base 18. The detachable structure of the scraper lining 19 can be that a clamping groove matched with the lining sheet body 191 is arranged on the base 18, a buckle is arranged on the upper part of the lining sheet body 191, and the scraper lining 19 is fixed on the base 18 by being clamped into the clamping groove through the buckle.
