Abstract
Abstract The invention is vacuum cleaner attachment for cleaning a surface within a confined space. In detail, the vacuum cleaner attachment fitting includes a first thin hollow rectangular member having a closed off first end and an open second end. A hollow tubular fitting is coupled to the second end for attaching to the vacuum hose of a vacuum cleaner. A second thin hollow rectangular member having open first and second ends, and top, bottom and side walls, is slidably engaged by its first end with the first end of the first member in a telescoping manner. The second end of the second member includes a plurality of vertical walls extending from the top wall to the bottom wall forming channels therebetween. The bottom wall is slotted between the vertical walls. Magnets are mounted on the side walls of the second member in proximity to the channels.
