Abstract
The disclosure relates to an electric buffing machine which is equipped with an X-shaped buffing pad that is mounted to a similarly X-shaped pad holder. 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 X-pad. The casing surrounding the pad has a specially designed tunnel-like spiral diffuser that guides the air currents entered into a collection box. The casing also has a flexible skirt mounted to the lower side thereof, extending around three-quarters of the casing periphery, which closes the gap between the casing and the floor. The chassis has two pairs of wheels and is designed so that when the buffing machine is turned off, the machine rests entirely on the wheels with the buffing pad raised off the ground. When the machine is turned on, the air currents pull the pad to the floor with a predetermined pressure.
