Abstract
A brush suitable for use with floor maintenance equipment and having both abrasive nonabsorbent bristles and nonabrasive absorbent bristles. The bristles are fairly evenly intermingled in each tuft, and the brush includes a plurality of tufts such that the brush face presents a substantially intermingled mix of both bristles. To enhance the cleaning qualities of the brush, the percentage of abrasive nonabsorbent bristles may be increased. To enhance the finish applying and buffing qualities of the brush, the percentage of nonabrasive absorbent bristles may be increased.
