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: There is provided a cleaning head for a surface treating appliance, comprising a suction chamber having a suction aperture, a brush bar arranged in the suction chamber and a comb having a plurality of teeth, each tooth extending into the suction chamber so that at least a distal end of each tooth is arranged to contact a portion of the brush bar. A contact face of each tooth is arranged to contact a radially extending portion of the brush bar and at least one corner between the contact face and a side face of the tooth includes at least one notch. Advantageously, the corner notches help break hair and other debris that might be wound on the brush bar and assists in entraining the hair or debris in the airflow through the suction aperture.

Abstract: A cleaner head for a vacuum cleaning appliance includes a housing, a front agitator and a rear agitator. A suction chamber is located between the front agitator and the rear agitator. A baffle is located within the suction chamber between the agitators. During use of the cleaner head, debris becomes entrained within air drawn towards the suction chamber. Guide members mounted on the housing guide the entrained debris towards the suction chamber, whereas the baffle guides the air upwardly towards a central suction port of the suction chamber.
