Abstract

A surface cleaning device includes a body, a suction opening, a suction source, and a separation chamber. The body has a handle and a receptacle. The suction source is at least partially located within the body. The suction source is in fluid communication with the suction opening and is operable to draw a fluid mixture of liquid and air through the suction opening. Liquid is separated from the fluid mixture in the separation chamber. The separation chamber is coupled to the body for rotation relative to the receptacle about a rotational axis. The separation chamber includes an inlet in fluid communication with the suction opening, an outlet in fluid communication with the suction source, and a drainage outlet in fluid communication with the receptacle.
