A vacuum cleaner hose assembly ( 3; 3'; 3'', 3 ''') has a flexible hose ( 5 ) that can be retracted by suction applied by the vacuum cleaner ( 1 ). The forward end of the hose ( 5 ) extends within a rigid cleaning wand ( 6, 6', 6'', 6 ''') and is attached to it close to its forward end so that a part of the hose can be stowed within the wand. The wand has two sections ( 64 and 65, 64 ' and 65 '), ( 64 '' and 65'', 64 ''' and 65 ''') telescopically slidable one within the other so that the wand can have an extended length or a shorter retracted length. Both sections of the wand have an open wall structure with one or two longitudinal struts ( 66 and 67, 72 ) and ( 73, 66', 73', 66'', 73 '') and one or two open windows ( 70, 76, 70'', 76 '') in order to reduce the weight of the wand.
