Abstract:
In one embodiment, a vacuum attachment for reaching smaller spaces has a gasket and narrow tubing. The gasket includes i. a cap member sized to fit over an open end of a vacuum hose, the cap member having an inner surface and a central hole to accommodate a narrow tube; ii. inner wall members extending from the central hole of the cap and gripping the narrow tube; and iii. outer wall members extending from the cap member perimeter to a distal edge and accommodating the vacuum hose, the wall members having an internal surface with ribs that extend from the distal edge of the wall members to and on the inner surface of the cap. The at least one narrow, bendable tube is fashioned to fit into the central hole of the cap member and has sufficiently thick walls to avoid collapse when a vacuum is applied thereto.
