Abstract: A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

Abstract: A cleaner head including a cleaner head body, a sole plate including a rear portion and flexible lateral side portions that define at least part of the periphery of a dirty air opening. The rear portion and the flexible lateral side portions are movable relative to the cleaner head body such that, in use, the rear portion and the flexible lateral side portions conform to a surface being cleaned in order to maintain a seal between the cleaner head and the surface.
