A pad driver assembly for a high speed floor burnishing machine includes a flexible or semi-rigid backing member with a pad beneath it and gripping projections for holding the pad in place. The backing member is provided with apertures so that when the pad assembly is driven at high rotational velocities beneath a shroud, air is drawn in through the apertures and forced radially outward in the pad, increasing the gripping action between the gripping projections and the pad, and also increasing the downward atmospheric pressure on the peripheral portion of the pad to promote increased polishing effectiveness.
