Abstract
A cleaner head for a cleaning appliance includes a housing, a sole plate for engaging with the floor surface, the sole plate comprising a suction opening through which dirt-bearing air enters the cleaner head, and a flexible annular seal located between the sole plate and the housing to allow the housing to move relative to the sole plate to reduce the force exerted on the sole plate by the housing, thereby allowing the sole plate to ride over the floor surface during a cleaning operation. The cleaner head includes at least one floor engaging support member connected to the housing for restricting the movement of the housing towards the sole plate to prevent the housing from pushing the sole plate against the floor surface.
