  • Patent number: 8776310
    Abstract: A cleaner head for a vacuum cleaner has a dirty-air inlet provided in a main suction chamber of the cleaner head, an outlet duct extending from the main suction chamber for connection to a suction source, and a rotating brush bar housed inside the main suction chamber for agitating a floor surface contacted through the dirty-air inlet. The brush bar is driven by an air-cooled motor housed inside a hollow section of the brush bar, the motor having an air intake and an air exhaust fluidly connected to one another to form an air cooling path through the inside of the motor. The air intake is connected to a clean air inlet on the cleaner head and the air exhaust is fluidly connected to the outlet duct by an exhaust duct which bypasses the main suction chamber.

  • Patent number: 8671514
    Abstract: A cleaner head for a cleaning appliance includes a rotatable agitator assembly, an agitator chamber housing the agitator assembly, and a sole plate defining a downwardly-directed opening through which debris energized by the agitator assembly enters the agitator chamber. A set of support members is located on a leading and trailing section of the sole plate, the support members extending downwardly beyond the sole plate to support the sole plate above a relatively hard floor surface. The lowermost extremities of the sets of support members are located in a first plane, and the edges of the opening are located in a second plane which is inclined upwardly relative to the first plane. The agitator assembly includes agitating members which extend outwardly from the opening beyond the second plane but within the first plane.

  • Patent number: 8671515
    Abstract: A cleaning device agitator system having an agitator and one or more cleaning members. The agitator has first and second ends, a longitudinal axis and one or more agitating devices. One or more friction surfaces may project from the spindle. The cleaning members are adjacent the agitator and adapted to move between a first position and a second position. In at least the second position, the cleaning members engage the agitator, such as by engaging the friction surfaces, to remove debris. Agitator and cleaning members may be incorporated into a cleaning head having an inlet nozzle and a chamber in which the agitator rotates, and there may be an activation mechanism using, for example, a resilient member to move the cleaning members. An overload protection device may be provided, and may adjust its sensitivity depending on whether the cleaning devices are in the first or second position.
