A scarifying machine is provided with a mounting plate having a plurality of downwardly open wells formed in it adjacent its periphery and that extend above the plane of the plate. Each well is defined and bounded by a pair of downwardly diverging, upwardly smoothly merging internal surfaces rendering the well non-clogging. A plurality of scarifying discs are mounted to the plate with the discs extending upwardly into the wells and downwardly beneath the mounting plate for contact with a floor.

A squeegee assembly having a tapered, flexible blade edge that will not develop a wary surface through use. The blade edge is formed on a flexible blade member, which blade member is disposed about and attached to another less flexible blade member. The flexible blade members may be symmetrically formed about a longitudinal axis, and the flexible blade member may include a blade edge formed on either side thereof. A blade support member having a shaped notch for receiving the flexible blade member provides longitudinal support therefor. The blade support member and flexible blade members are held and supported by a handle and trigger assembly having trigger actuated jaws.

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.
