1. In a high speed floor burnishing machine, the combination comprising a pad driver assembly including a pad adapted to contact the floor;
- a motor for rotating said pad driver assembly at high angular velocity;
means for generating a continuous air flow outwardly of said rotating driver assembly for entraining debris generated by said rotating driver assembly;
shroud means enclosing said driver assembly;
collection means including a filter in fluid communication with said shroud means for receiving said air flow and entrained debris and defining a generally upright wall having at least a portion being generally cylindrical for routing said air and entrained debris in a generally circular pattern, and further including an upwardly inclined surface for further routing said air toward said filter for filtering out dust and light material from said air, and means for trapping heavier material adjacent the termination of said upwardly inclined surface.

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.
