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.
