Abstract: The present disclosure provides a cleaning device comprising a body, a suction source, and a suction head operably coupled to the body and defining at least one suction opening in fluid communication with the suction source. The suction opening intakes debris from a surface to be cleaned. The suction head comprises a wall, an agitator configured to agitate the surface, and a fluid dispenser configured to dispense fluid onto a portion of the wall prior to making contact with the surface.

Abstract: An extraction cleaner may include an upright body, a cleaning head pivotally coupled to the upright body, a supply tank coupled to the upright body and fluidly coupled to the cleaning head, a recovery tank coupled to the upright body and fluidly coupled to the cleaning head, and an agitator rotatably coupled to the cleaning head. The agitator may include a main body and a bristle strip extending helically around the main body and forming an acute attack angle with the main body that opens in a direction of rotation of the agitator during a cleaning operation of the extraction cleaner.
