The wiping object is pressed against the water removal members <NUM>, at this moment, the water removal members <NUM> are driven by an external force to rotate or the wiping object moves, so that the wiping object is cleaned by the water removal members; when the wiping object is completely cleaned, the water feeding mechanism <NUM> stops conveying water, so the wiping object is no longer cleaned with water and is still pressed against the water removal members <NUM>, at this moment, the water removal members are driven by an external force to rotate to scrape and squeeze the wiping object, water left in the wiping object is squeezed out, and water removal of the wiping object is completely.

The water removal members <NUM> are any one or a combination of strips and rollers, so that the diversity of the cleaning device is improved.

Preferably, when water is removed, the water feeding mechanism <NUM> stops conveying water to the wiping object, water removal members <NUM> keep static, and the wiping object of the floor mopping machine moves and scrapes with the water removal members <NUM>, so that water on the wiping object is removed. According to another preferred implementation, the water removal members <NUM> are driven by a motor w40 and scrape with the wiping object of the floor mopping machine. In this solution, the water removal members <NUM> are powered to move to remove water from the wiping object.

According to another implementation of the water feeding mechanism <NUM>, the water feeding mechanism <NUM> comprises a bucket body <NUM>, the bucket body <NUM> is connected to a water inlet pipe w16 for conveying cleaning water to the wiping object, and the bottom of the bucket body <NUM> is higher than a water outlet of the water inlet pipe w16.
