A multi-purpose vacuum cleaner nozzle has a flat surface tool and a brush at the vicinity of a suction inlet for respectively cleaning rugs and floors. The flat surface tool and brush are movable with respect to one another and alternately moved into cleaning position by mechanism having a single operating member movable forward and backward between first and second positions and to which an external force only can be applied in one direction to impart movement thereto from its first to a second blocked position to bring the brush into cleaning position. The operating member cannot be moved directly from its second blocked position to its first position. The operating member can only be returned to its first position by initially moving it in the same one direction beyond the second blocked position to a third position. When the operating member, which is resiliently biased to its first position, is released after it has been moved to its third position, it can bypass the second blocked position and return to its first position to bring the flat surface tool into cleaning position. |
