Abstract: A vacuum cleaner has an agitator assembly that is coupled to a motor via a belt, and a belt shifting assembly which has a belt shifter which moves the belt between engagement with a drive pulley or an idler pulley on the agitator assembly. A biasing member biases the belt shifter between engagement with the drive pulley and the idler pulley.

Abstract: A vacuum cleaner has an agitator assembly, a belt drive system coupling the agitator assembly to a motor via a belt, and a belt shifting assembly which selectively shifts the belt between a drive pulley and an idler pulley on the agitator assembly. Trace rotational force transmitted to the agitator assembly when the belt is on the idler pulley is prevented from causing the agitator assembly to rotate by an anti-rotation member of the belt shifting assembly.

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: 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 belt drive disengaging assembly for a vacuum cleaner includes a pivoting belt tensioner and an actuator assembly, wherein movement of the actuator assembly selectively pivots the belt tensioner to place tension on a belt coupled between an agitator and source of driving power, thereby coupling the agitator with the source of driving power.

Abstract: A modular auxiliary brush assembly for a vacuum cleaner includes a mounting bracket coupled to the vacuum cleaner, a spring-biased brush head, and a shaft which mounts the brush head to the mounting bracket. The spring-biased brush head is vertically adjustable to accommodate cleaning surfaces of varied heights and textures. The spring-biased brush head includes a tread which contacts a surface to be cleaned and rolls the brush head relative to the vacuum cleaner when the vacuum cleaner moves over the surface.

Abstract: A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air and a collection chamber for collecting dust and debris that is separated from the air in the cyclone separation chamber. The cyclone module assembly further includes at least one feature for directing contaminants downwardly, such as a helical step dividing the separation chamber from the collection chamber or a circumferential fin that extends from the inside wall of the collection chamber or.

Abstract: A vacuum cleaner comprises a user-controllable clutch assembly for selectively engaging an agitator assembly. The clutch assembly generally comprises an axially displaceable drive member that is selectively engageable by rotating ramps that engage stationary cam lobes. In one embodiment, the clutch module is mounted to the foot housing and is intermediately connected between the vacuum motor/fan shaft and the agitator. In a second embodiment, the clutch module is mounted axially on the agitator shaft. In a third embodiment, a linkage interconnects a handle detent pedal to the clutch module to automatically engage the clutch when a user depresses the detent pedal.
