摘要： A surface cleaning apparatus, such as a carpet extractor, includes a base and a fluid recovery system for drawing dirty cleaning fluid from a surface to be cleaned. The fluid recovery system includes a suction nozzle in fluid communication with a recovery chamber. The suction nozzle is mounted to the base for vertical movement with respect to the base and is biased into contact with the surface to be cleaned.

摘要： An extraction cleaner for a floor surface comprises a portable extractor 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. The portable extractor includes a suction hose for manually suctioning fluid from the floor surface, a recovery tank interconnected to the suction hose for receiving recovered fluid from the floor surface, and a fluid delivery system for dispensing a cleaning fluid onto the floor surface. One or more connections are made between the base and components of the portable extractor when the portable extractor is operably mounted to the base.

摘要： An extraction cleaner for cleaning a floor surface includes a liquid distribution system and a liquid recovery system. The liquid recovery system includes a motor, and a motor cooling air pathway provides cooling air to the motor and removes heated cooling air from the motor. A duct system delivers heated motor cooling air to a supply tank of the extraction cleaner to heat liquid contained therein, and also drains liquid from the supply tank away from the motor.

摘要： A surface cleaning apparatus is provided with a nozzle cover having multiple functions, including sealing an opening for an above-the-floor vacuum hose, aiding in removal of a suction nozzle from the apparatus and acting as a handle for the suction nozzle upon removal of the suction nozzle from the apparatus. A locking mechanism prevents the suction nozzle from accidentally releasing from the apparatus when the vacuum hose is installed.
