Abstract
A suction cleaner adapted for either on the floor cleaning or above the floor cleaning includes a base having a nozzle and a handle pivotally secured to the base so as to be pivotable between a use position and a non-use position. A suction passageway is located in at least one of the base and the handle and communicates with the nozzle. A valve is rotatably mounted in the suction passageway for selectively closing the suction passageway. An elevating mechanism selectively elevates the nozzle away from, and lowers the nozzle towards, a subjacent support surface, the mechanism being secured to the base. An actuating mechanism manually actuates the elevating mechanism. The actuating mechanism is secured to at least one of the base and the handle and engages both the valve and the elevating mechanism. The actuating mechanism is selectively engaged by a portion of the handle so that when the handle is pivoted to the non-use position, the actuating mechanism drives the elevating mechanism to elevate the nozzle from the subjacent floor surface and also drives the valve to close the suction passageway.
