First Claim
1. A cleaner head for a vacuum cleaner, comprising:
- an agitator in the form of a brush bar, the brush bar comprising a plurality of radially extending bristles and a sealing material disposed between the bristles, the sealing material extending over substantially the entire circumferential and axial extent of the regions of the brush bar between the bristles, wherein the sealing material comprises a tufted material;
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 such that the brush bar seals against the housing thereby restricting flow of air through the front opening.
