A vacuum sweeper is cantilevered to a hinged bracket mounted to the front of a conventional automatic floor scrubber. The sweeper includes a vacuum head, an overlying debris ramp, and two vertically rotating, conical brushes having their base ends in contact with the floor. The base end of the conical brushes sweep a path at the edge of the vacuum sweeper in excess of the width of the scrubber. The entire vacuum sweeper apparatus is mounted for vertical excursion relative to the cantilevered mount to the hinge bracket to enable up and down excursion of the sweeper and vacuum responsive to either scrubber motion or inevitable floor irregularities encountered during floor scrubbing. Where vacuuming is not required in advance of scrubbing, such as during double scrubbing or floor stripping cycles, provision is made to hinge the vacuum sweeper upwardly away from floor engagement. A ramp is used in conjunction with the vacuum for collecting large debris.
