Abstract
A rotary brush assembly for treating a surface has a circular disk having a generally fiat first side and a second side. A plurality of elongated fibers are individually attached to the first side of the disk and positioned generally parallel to one another and perpendicular to the first side of the disk. The unattached ends of the fibers collectively define a generally planar treatment surface adjacent and generally parallel to the first side of the disk. The fibers are positioned such that the fibers form areas of filled space on the treatment surface, the areas of filled space separated by areas without fibers.
