Abstract: A high speed floor buffing machine equipped with a pad holder for an X-shaped buffing pad is disclosed. The arms of the pad holder have a wedge-shaped cross section that acts as an air foil to create air currents that flow up between the arms of the buffing pad. The casing surrounding the pad has a specially designed tunnel-like spiral diffuser that guides the air currents into a collection box. The casing also has a flexible skirt mounted to the lower edge thereof, extending around three-quarters of the casing periphery, and closing the gap between the casing and the floor. The chassis has two pair of wheels and is designed so that when the buffing machine is off, the machine rests entirely on the wheels with the buffing pad raised off the floor, and when the machine is on, the air currents urge the pad against the floor with a predetermined pressure. Alternate embodiments of the pad holder are disclosed.
