Abstract
A handheld extractor that includes a housing, a supply tank adjacent a first side of the housing, and a recovery tank adjacent a second side of the housing. A cleaning chamber is in the third side of the housing. A fluid flow path is between the supply tank and the cleaning chamber. The cleaning chamber receives a suction nozzle and a suction source provides suction through a hose and the second fluid flow path to extract the cleaning fluid from the supply tank, along the fluid flow path into the cleaning chamber, through the hose and into the recovery tank to flush the cleaning fluid through the hose to clean the hose when the suction nozzle is received in the cleaning chamber.
