Claims20
An extraction cleaner, comprising:
- a portable extractor comprising:
- a housing having a suction source;
- a suction hose interconnected to the suction source for manually suctioning fluid from a floor surface;
- a recovery tank interconnected to the suction hose for receiving recovered fluid from the floor surface;
- a fluid delivery system for dispensing a cleaning fluid onto the floor surface;
- and
- a first recovery connection fluidly interconnected with the recovery tank;
- and
- a base adapted to be moved to perform a cleaning operation on the floor surface when the portable extractor is operably mounted to the base, and the base comprising:
- a suction nozzle juxtaposed with the floor surface;
- a second recovery connection fluidly interconnected with the suction nozzle and adapted to be connected with the first recovery connection when the portable extractor is operably mounted to the base, such that the suction source is fluidly interconnected to the suction nozzle by the interconnection of the first and second recovery connections;
- and
- a diverter valve for selectively fluidly interconnecting the recovery tank with one of the suction hose and the suction nozzle, the diverter valve, comprising:
- a follower provided on one of the portable extractor and the base;
- and
- a cam provided on the other of the portable extractor and the base wherein the cam is configured to be abutted with the follower upon interconnection of the first and second recovery connections, such that the diverter valve opens fluid communication between the recovery tank and the suction nozzle when the portable extractor is operably mounted to the base.
