摘要： A window washing accessory cleaning tool adapted for use with a water extraction cleaning machine has a solution spray nozzle integrated therewith and a combination suction and scrubbing head rotatably mounted with respect to the solution spray nozzle. The cleaning solution spray nozzle is provided on one side of a dual conduit support member and a head is rotatably mounted to the dual conduit support member. A foam applicator/scrub pad is provided along one end of the head and a suction nozzle opening defined by a squeegee blade and a rigid flange are provided one the other side of the head. With this structure, the applicator/scrub pad and suction nozzle can be rotated with respect to the cleaning solution spray nozzles, thereby making the accessory cleaning tool adaptable for a wide variety of cleaning operations. Preferably, the window washing accessory cleaning tool is removably mounted to the end of the flexible hose.

摘要： A handheld liquid extraction cleaner includes a recovery tank mounted to the forward end of a cleaner housing with a suction nozzle and conduit on a front face of the recovery tank connected to an inlet opening in the recovery tank. A vacuum source is connected to the recovery tank through an exhaust conduit, integrally formed in the recovery tank, for drawing liquid and debris through the suction nozzle and the suction conduit and into the recovery tank A removable cleaning fluid supply tank is mounted to a rear portion of the cleaner housing, an adjustable spray nozzle is mounted to the suction conduit and a pump is positioned in a supply conduit between the spray nozzle and the cleaning fluid supply tank for supplying pressurized cleaning fluid from the cleaning fluid supply tank to the spray nozzle The pump includes an impeller which is positioned in an outlet opening of a reservoir in which the cleaning fluid is deposited from the cleaning fluid supply tank. Accessory tools are releasably mounted to the cleaner housing and the recovery tank housing. A scoop is removably mounted to the rear of the cleaner housing. A storage base for the cleaner has a retainer for removably supporting the handheld cleaner and a recess for releasably storing accessory tools in the storage base.
