A brush bar including a central core in the form of a rigid tube, a plurality of outwardly extending bristles in the form of at least one bristle strip, and a sealing material extending over substantially the entire remaining circumferential and axial extent of the brush bar, the at least one bristle strip having a root portion which is sandwiched between the sealing material and the central core or which is attached on top of the sealing material.

Cleaner head for a vacuum cleaner

A cleaner head for a cleaning appliance includes a rotatable agitator and an agitator chamber housing the agitator. The agitator includes a flexible body and surface engaging members mounted on the body. The agitator chamber includes a downwardly-directed opening through which debris energized by the surface engaging members enters the cleaner head. The opening is located in a plane. The cleaner head includes a drive mechanism for rotating the agitator about a rotational axis which is inclined both relative to the plane of the opening and towards the rear of the opening so that, with rotation of the agitator, the surface engaging members protrude through the opening towards the front of the opening.

Cleaner head

A cleaner head for a vacuum cleaning appliance includes a first rotatable agitator and a second rotatable agitator for sweeping debris from a surface, each agitator comprising a disc-shaped body and a plurality of resilient members, preferably in the form of bristles, mounted on the body for engaging the surface. The agitators are housed within an agitator chamber which includes a downwardly-directed opening through which debris energized by the bristles enters the cleaner head. The opening is located in a plane, and each body is inclined relative to the plane of the opening so that, with rotation of the agitator, the bristles protrude through the opening. The bristles of the first agitator are angularly offset from the bristles of the second agitator.

A cleaner head for a cleaning appliance includes a rotatable agitator and an agitator chamber housing the agitator. The agitator includes a drive shaft, a flexible body connected to the drive shaft and surface engaging members mounted on the flexible body. The agitator chamber includes a downwardly-directed opening through which debris energized by the surface engaging members enters the cleaner head. The opening is located in a plane relative to which the flexible body is inclined so that, with rotation of the agitator, the surface engaging members protrude through the opening, preferably towards the front of the opening.
