<p>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.</p> |
