Patent number: 8495790Abstract: A cleaner head for a cleaning appliance includes a rotatable agitator and an agitator chamber housing the agitator. The agitator includes a flexible body and surface engaging members mounted on the body. The agitator chamber includes a downwardly-directed opening through which debris energized by the surface engaging members enters the cleaner head. The opening is located in a plane. The cleaner head includes a drive mechanism for rotating the agitator about a rotational axis which is inclined both relative to the plane of the opening and towards the rear of the opening so that, with rotation of the agitator, the surface engaging members protrude through the opening towards the front of the opening.Type: GrantFiled: December 14, 2011Date of Patent: July 30, 2013Assignee: Dyson Technology LimitedInventors: Steven John Forbes, Spencer James Robert Arthey, Jean-Paul Mark Iles
