Abstract
A high speed floor burnisher has a pad assembly rotating at high speed in a vacuum shroud which is evacuated by forced air without a separate vacuum motor. The evacuated air and entrained dust and debris are routed to a filter assembly with a replaceable filter and a removeable receptacle provided with a trap for larger particles so that they do not plug the filter, and thereby prolong its useful life.
