    Abstract: A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

    Abstract: A cleaning appliance having a cleaner head rotatably attached to a duct. The cleaner head includes a main body having an agitator chamber, an agitator rotatably mounted within the agitator chamber, and a drive assembly coupled to the agitator such that torque generated by the drive assembly is transmitted to the agitator. The drive assembly is located within the agitator such that the centre of gravity of the cleaner head is located on or near a vertical plane containing the rotational axis about which the cleaner head rotates relative to the duct.

    Abstract: The invention relates to a cleaner head for a vacuum cleaner. The cleaner head has a housing and a soleplate assembly hingedly connected to the housing. The soleplate assembly and the housing are held closed by a releasable catch, which is pivotally mounted to one of the housing or the soleplate for rotation between a locking position and a release position. In accordance with the invention, the catch incorporates a first cam, which cam engages the other of the soleplate or the housing as the catch is rotated from the locking position towards the release position, in order to force apart the housing and the soleplate.

    Abstract: A cleaner head for a vacuum cleaner houses a hollow brush bar mounted for rotation about an axis. This brush bar is driven by a motor housed inside the hollow brush bar, the motor forming part of a drive assembly supported at one end of the cleaner head. The brush bar is arranged for removal from the cleaner head by sliding the brush bar along the axis and out through an opening at the opposite end of the cleaner head and the brush bar is rotatably supported in clearance around the drive assembly by a first bearing, which bearing engages the brush bar in a corresponding axial-sliding fit to allow said sliding removal of the brush bar.

    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.
