    Abstract: A floor cleaner including a vacuum source recovery tank or collection bin and a body pivotally coupled to a base. The body is pivotable between an upright storage position and an inclined operating position and the body includes a recovery tank recess. The floor cleaner further includes a recovery tank removably coupled to the body in the recovery tank recess, the recovery tank in fluid communication with a vacuum source and a suction inlet, the recovery tank configured to store the cleaning fluid and/or debris drawn through the suction inlet from a surface by the vacuum source. The floor cleaner further includes a projection and a recess that receives the projection when the recovery tank is coupled to the body to limit movement of the body relative to the recovery tank.

    Abstract: A vacuum cleaner that includes a surface cleaning head including a dirty air inlet, a brush supported by the surface cleaning head, a motor coupled to and operable to cause movement of the brush, a sensor to sense a voltage associated with a current of the motor, and a controller configured to control an amount of current provided to the motor in response to the sensed voltage. The controller is configured to control a first pulse width modulated (PWM) duty cycle provided to the motor when the sensed voltage is less than a reference voltage, control a second PWM duty cycle provided to the motor when the sensed voltage is greater than the reference voltage, the second PWM duty cycle being less than the first PWM duty cycle, and turn off the motor when the sensed voltage increases to a voltage associated with an overload current of the motor.

    Abstract: A handheld extractor that includes a housing, a supply tank adjacent a first side of the housing, and a recovery tank adjacent a second side of the housing. A cleaning chamber is in the third side of the housing. A fluid flow path is between the supply tank and the cleaning chamber. The cleaning chamber receives a suction nozzle and a suction source provides suction through a hose and the second fluid flow path to extract the cleaning fluid from the supply tank, along the fluid flow path into the cleaning chamber, through the hose and into the recovery tank to flush the cleaning fluid through the hose to clean the hose when the suction nozzle is received in the cleaning chamber.

    Abstract: An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.

    Abstract: A floor cleaner including a base movable over a surface to be cleaned, the base including a front side, a back side opposite the front side, and a brushroll chamber. A supply tank is configured to store a cleaning fluid and a distribution nozzle is in fluid communication with the supply tank, the distribution nozzle operable to dispense the cleaning fluid onto the surface to be cleaned. A brushroll cover is removable from the base to access the brushroll chamber. A brushroll is within the brushroll chamber. The distribution nozzle is disposed adjacent the front side of the base and carried on an upper exterior portion of the base and configured to spray forwardly of the base in a direction from the back side toward the front side.

    Abstract: A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway.
