Abstract: The invention provides a cleaner head (50;90;130;180) for a vacuum cleaner comprising a housing (52;92;132;182), a suction opening (60;100;142;184) in a face (58;96;136;186) of the housing which is intended to face a floor surface, a suction passage (110;146) for conducting dirt-laden air from the suction opening (60;100;142;184) through the cleaner head to an outlet thereof, a bleed air inlet (200) arranged in the housing and closed by a bleed valve (76;124;166;198) which is openable to allow air to be bled into the suction passage via the bleed air inlet. The cleaner head further comprises a force-transmitting member (68 122;152;194;232) connected to, or adapted to be connected to, a handle (18;48) by means of which the cleaner head is, in use, maneuvered across the floor surface, and the force-transmitting member (68;122;152;194;232) is connected to the housing by a connection allowing relative movement between the force-transmitting member and the housing.

Abstract: A cleaning head (30) for a vacuum cleaner comprises a housing (305) which extends transversely to the direction of intended movement (A) of the head. A row of bristles (310) extend outwardly from the sides of the housing (305). The bristles (310) extend transversely outwardly and forwardly from the housing and extend to a level beneath the lowermost surface of the housing. Dirt, dust and other debris which collects at the very edge of a room is either ‘guided’ out of the region next to the wall or is subjected to a vigorous ‘flicking’ action as the head (30) is moved across the floor. A suction channel (330) is located adjacent to the bristles. The bristles (310) are provided as a unit which is removable from the head (30).
