Abstract: A cleaner head for a vacuum cleaner including an agitator in the form of a brush bar, the brush bar including a plurality of radially extending bristles and a sealing material disposed between the bristles. The sealing material extends over substantially the entire circumferential and axial extent of the regions of the brush bar between the bristles. The cleaner head further includes a housing defining a chamber which at least partially surrounds the brush bar, a dirty air inlet in a lower part of the chamber and a front opening that exposes the brush bar at the front of the housing. The brush bar is supported for rotation with respect to the housing and arranged in the chamber such that the brush bar seals against the housing thereby restricting flow of air through the front opening.

Abstract: A cleaner head that includes an agitator in the form of a brush bar, the brush bar including a sealing material extending over the circumferential and axial extent of the brush bar, the sealing material including a tufted material, and a housing defining a chamber which at least partially surrounds the brush bar, a dirty air inlet in a lower part of the chamber and a front opening that exposes the brush bar at the front of the housing, the brush bar being supported for rotation with respect to the housing and arranged in the chamber, wherein a partition is arranged within the chamber between the brush bar and an outlet of the chamber, the partition extends transversely and divides the chamber into an agitating region and a settling chamber, and the partition includes a wall that extends tangentially to the brush bar and is inclined rearwardly.

Abstract: A cleaner head for a vacuum cleaner, comprising an agitator; and a housing defining a chamber which at least partially surrounds the agitator, a dirty air inlet in a lower part of the chamber and a dirty air outlet, wherein a partition is disposed between the agitator and the dirty air outlet such that the partition and the housing define a settling region of the chamber adjacent the dirty air outlet, the partition is provided with a first debris opening and a second debris opening disposed above the first debris opening such that, in use, debris swept past the first debris opening by the agitator is swept towards the second debris opening.
