Abstract
The disclosed cleaning device has a suction unit that can be used to take in liquid, a tank that can be used to hold the liquid, a mouth that can be used to pour liquid from the tank, and wheels that form a base. It also has a pivot that can be used to rotate the tank between a normal use position and a pouring position. The pivot is arranged so that in the pouring position, the center of gravity of the unit remains within the horizontal range of the base, even as the mouth of the tank falls outside the horizontal range of the base. As shown, the pivot is 12 inches above the floor and within the horizontal range of the base. In this position, it remains laterally between the center of gravity of the tank and the edge of the base when the tank is emptied.
