A cleaner head for a vacuum cleaning appliance includes a first rotatable agitator and a second rotatable agitator for sweeping debris from a surface, each agitator comprising a disc-shaped body and a plurality of resilient members, preferably in the form of bristles, mounted on the body for engaging the surface. The agitators are housed within an agitator chamber which includes a downwardly-directed opening through which debris energized by the bristles enters the cleaner head. The opening is located in a plane, and each body is inclined relative to the plane of the opening so that, with rotation of the agitator, the bristles protrude through the opening. The bristles of the first agitator are angularly offset from the bristles of the second agitator.
