A vacuum cleaner hose has a rigid cleaning wand ( 21 ) with a valve ( 26 ) and a flexible hose ( 30 ) that can be retracted by suction pressure when the valve ( 26 ) is closed. The hose ( 30 ) extends within the wand ( 21 ) and is secured at its forward end ( 31 ) adjacent the forward end of the wand. A flexible sleeve ( 40 ) is joined at one end with the vacuum cleaner ( 1 ) and extends along the rear part of the hose ( 30 ) so that it can be attached to the rear end of the wand ( 21 ) when the hose is retracted, to retain it in a retracted state.
