ABSTRACT:
A vacuum cleaner tool is removably mounted on the elongated wand of a conventional vacuum cleaner. The tool includes a head or main housing having a forwardly-disposed brush enclosure portion with a lower planar opening formed therein. A brush is rotatably journaled in the brush enclosure portion of the housing and protrudes below the opening therein. An air turbine is rotatably journaled in the housing and is drivingly connected to the brush. The axis of the housing is coincident with the axis of the wand, and both are arranged at 45 degrees with respect to the planar opening for the brush. In one position, the planar opening is in a horizontal plane. The mounting means between the housing and the wand includes a swivel member. This swivel member enables the housing to be rotated 180 degrees with respect to the wand. When so rotated, the planar opening for the brush is in a vertical plane. As a result, the tool facilitates the cleaning of horizontal and vertical surfaces (such as stair steps) without requiring the operator to change the orientation of the wand with respect to the working surfaces.
