Abstract: A cleaner head for a cleaning appliance, the cleaner head including a main body having an air inlet and an air outlet, an agitator supported for rotation with respect to the main body about a rotational axis, and a collector for collecting strands of hair. The collector is supported by the main body and arranged such that strands of hair drawn through the air inlet wrap around at least part of the collector. The collector is movable with respect to the main body between a hair collecting position in which the agitator is rotatable with respect to the collector and a hair removal position.
