Abstract: An apparatus for application to a broom that includes a broom head provides enhanced cleaning. A skirt of polar fleece fabric has a yoke long enough so that one end of the polar fleece fabric laps the other end when wrapped around the broom head. Hook and loop fasteners on the yoke where one end laps the other end enable the skirt to remain wrapped around the broom head. A plurality of strips that are at least one to three inches longer than the height of the broom head and bristles depend from the yoke. The skirt of polar fleece fabric yoke and strips are conveniently made of a single piece of fabric. A fabric with a stretchable direction transverse to a non-stretchable direction works best if the yoke is substantially parallel to the non-stretchable direction.
