A burnishing apparatus having at least one burnishing disc engageable with a floor includes a shroud surrounding the burnishing disc. The shroud defines a vacuum zone in fluid communication with a filtration system. The filtration system has an inlet, wherein the vacuum zone is in fluid communication with the inlet. In one embodiment, a vacuum source is in fluid communication with the inlet, wherein the vacuum source draws dust from the vacuum zone into the filtration system through the inlet, and at least some of the dust is collected by the filtration system. In another embodiment of the invention, an agitation device regenerates at least one filter element forming part of the filtration system.
