Abstract: A vacuum accessory tool comprises a housing that defines a suction nozzle and a hair removal assembly associated with the suction nozzle. In one embodiment, the vacuum accessory tool further comprises an agitator assembly located in the suction nozzle and driven by an air turbine. In another embodiment, an impeller associated with the air turbine is weighted to prevent build-up of hair and other debris at the impeller.

Abstract: A brushroll for a vacuum cleaner includes a dowel defining a central rotational axis about which the brushroll rotates, at least one bristle stiffener, a plurality of first bristles protruding from the dowel adjacent to the bristle stiffener, and a counterbalance which is positioned relative to the bristle stiffener to rotationally balance the brushroll, wherein the cross-sectional shape of the dowel is asymmetrical.

Abstract: An accessory tool can include a recovery tank assembly for removing fluid and dirt from a surface to be cleaned and store the recovered fluid and dirt. The accessory tool can be used in connection with a vacuum cleaner including an extraction cleaner. The accessory tool can include a housing assembly having a suction outlet opening adapted to be connected to a vacuum hose in fluid communication with the suction source of the vacuum cleaner and a recovery tank can be in fluid communication with the suction nozzle to store liquid drawn in through the suction nozzle.

Abstract: A vacuum cleaner with a separation module comprises an exhaust grill positioned fluidly between a separator chamber and an air outlet. The exhaust grill can comprise a body having a plurality of louvers and a plurality of inlets defined between adjacent louvers.

Abstract: A vacuum cleaner and vacuum cleaner system comprises a dirt separating and collecting system. The dirt separating and collecting system can include a filter module having a filter bag, wherein the inlet to the filter bag is helical and dirt entering the filter bag is visible to the user. Optionally, the filter bag filter module can be interchanged with a bagless filter module, which may include a conventional cyclone separator.

Abstract: A bare floor cleaner has a foot with a dry suction nozzle and a handle assembly pivotally connected to the foot assembly. A diverter mounted in the working air conduit between the foot assembly and the handle assembly is movable by movement of the handle assembly between a dry suction position and a wet mop position for selectively at least partially blocking working air flow from the dry suction nozzle to a collection assembly. A fluid delivery system includes a user operated trigger for actuating the fluid delivery system to distribute fluid in the wet mop position and deactivating a motor/fan assembly. A trigger lock prevents cleaning solution from being distributed when the handle is in dry mode position. The fluid delivery system includes a heating element to raise the temperature of the cleaning solution before it is distributed to the surface to be cleaned. Support glides on the foot reduce the surface area contact between the foot pad and the surface to be cleaned.

Abstract: 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, wherein the portable extractor can be used as a standalone extractor when detached from 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.

Abstract: A vacuum cleaner comprises a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly carried by the cleaning head and having a hair collection element adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned.

Abstract: A housing has a suction inlet thereon and a suction source associated with the housing, in fluid communication with the suction inlet to produce a working airflow therethrough and a dirt container in fluid communication with the suction inlet and suction source. The housing further comprises a body defined by a central portion and a pair of extension arms that extend laterally outwardly from the central portion, wherein each extension comprises a mount, which receives a rotatable agitator thereon. A drive assembly is configured to counter-rotate each agitator with respect to the other agitator, and wherein the suction inlet is positioned on the housing rearward of, and between, each of the axes of rotation of each agitator. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris outside the periphery of the housing along a converging debris path, towards the suction inlet.

Abstract: A vacuum cleaner has a separation/collection module for separating dirt and other contaminants from a dirt-containing working airstream and collecting the separated dirt. The module can include at least one cyclonic separation stage and an exhaust grill fluidly positioned between the separation stage and an air outlet from the collection module.

Abstract: A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.

Abstract: 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.

Abstract: A vacuum cleaner has a cyclone separator for separating dirt and other contaminants from a dirt-containing working airstream and a collection chamber collecting the separated dirt. The vacuum cleaner can further include handle defining a fines catcher downstream of the cyclonic separation stage for collecting fine dirt, where the handle can be used to remove the fines catcher and/or an exhaust grill from the cyclone separator.

Abstract: A cleaning composition for treating a surface comprises a purified enzyme and an enzyme denaturant system. The enzyme denaturant system is configured to denature the purified enzyme such that any residue remaining on the surface after the treatment of the surface is virtually free of active purified enzymes.
