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.
