ABSTRACT:
A cleaner attachment for use with a vacuum source, such as a common vacuum cleaner or a central vacuum system, defined by a plurality of feathers arranged about the end of a tube defining the body of the attachment. The feathered covered end of the tube includes a series of openings along both the side wall and the end wall thereof, creating a vacuum type atmosphere with the feathers. In a typical assembly, the quills of the feathers are wire wrapped into position on the tube, and the wire wrapping overlaid by a heat shrinking material.
