ABSTRACT:
A brushroll for a vacuum cleaner includes a cylindrical dowel having a number of holes drilled thereinto. The holes are formed into a first row and a second row, the two rows being closely spaced in relation to each other. First tufts are secured in each hole of the first row and second tufts are secured in each hole of the second row. The tufts can be made of the same type of bristle or of different types of bristles. The tufts of the first row are supported by the tufts of the second row during a cleaning rotation of the brushroll. Preferably, the tufts of the second row are located at between 1/4 and 3/4 of a free length of the first row of tufts. The bristles of the second row are shorter than the bristles of the first row. If desired, a third row of tufts may also be provided. The rows of tufts can extend helically around the dowel.
