Abstract
An extractor-type surface cleaning machine includes a base or foot having a suction nozzle and a handle that is pivotally coupled to the foot and moveable between upright and inclined positions. The recovery tank is removably securable to the foot and fluidly communicates with the suction nozzle and the accessory. The recovery tank defines a collection chamber and a passage having an inlet in communication with the suction nozzle and an outlet. A valve member is moveable between a closed position substantially covering the outlet and an open position. Movement of the handle to the upright position moves the valve member to the closed position to block the passage during cleaning with the accessory hose. Movement of the handle to the inclined position allows movement of the valve member to the open position so that suction from the collection chamber is communicated to the suction nozzle for floor cleaning.
