ABSTRACT:
A ribbon of flexible fabric (e.g., nylon) is folded and riveted near the fold to form an attachment loop. The loop is then coupled on a centrally located support rod inside an air duct, the ribbon ends extending beyond the exit of the duct. When air is forced through the duct, the free ends oscillate rapidly to brush away particulates on a surface being cleaned. The support rod is a portion of a clip which is removably coupled to the duct. The duct is cylindrical and may comprise a common, commercially available vacuum cleaner tube.
