A cleaner head for a vacuum cleaner has a housing (12, fig. 1), an agitator (20) rotatably mounted within the housing, and first (56) and second (58) debris removal members. The first debris removal member is movable relative to the second debris removal member between a first position in which a debris collection channel (88) is defined, and a second position (fig. 16) in which the debris removal members are contiguous or overlapping, wherein movement from the first to the second position removes debris from the channel, movement of the first debris removal member is governed by rotation of the agitator. The mechanism may move the first member to the first position when the agitator moves at a speed above a pre-determined threshold and may move it to the second position when the agitator speed drops below a pre-determined threshold. The mechanism may comprise a weight (62, fig. 11) attached to the first member. The first member may be pivotally mounted to the second member. The first and second members may be removable from the cleaner had independently of the agitator. There may be a first and second further debris removal members defining a further channel (fig. 19).
