ABSTRACT:
A fabric covering adapted to be placed over the suction head of a conventional electric broom to prevent the scratching and/or marring of a non-carpeted floor surface. The fabric covering includes first and second opposed openings formed therethrough. The first opening includes an elastic band positioned in a peripheral hem to gather the covering about the suction head. The second opening is substantially, identically shaped as the suction opening formed in the bottom surface of the suction head. Therefore, once the covering is placed over the suction head, no portion of the suction head can contact either the floor surface or any inanimate objects which may be contacted when the electric broom is moved about the floor.
