Claim:
Cleaning apparatus comprising a support member supporting a plurality of cleaning members for rotational movement, transmission means engaged with each cleaning member and for converting a driving force into rotation of the cleaning members, each cleaning member being movable relative to said support member between an extended position and a first retracted position whereby the cleaning members remain in driving engagement with said transmission means in both positions, characterised in that each cleaning member is movable to a second retracted position where it is closer to the support member than when in said first retracted position and is disengaged from said transmission means so that it is not driven in rotation, wherein each cleaning member comprises a shaft that is received in a sleeve, the shaft defining a longitudinal axis and being axially movable relative to the sleeve, an outside surface of the sleeve defining the transmission means, the sleeve being supported in an aperture in the support member, the sleeve being rotatable in said aperture.
