Mobile surface cleaning and polishing apparatus

摘要

A mobile floor cleaning and polishing apparatus is readily movable along the floor or horizontal surface to be treated to effect cleaning and polishing of a large metallic surface such as a ship deck. The apparatus comprises a mobile frame assembly having a centrifugal projector mounted thereon for impelling abrasive particles against the surface, a magnet drum for attracting and collecting the used abrasive particles accumulated on the surface, and a vacuum suction system for recovering heavy or large particles not recovered by means of the magnet drum. The vacuum suction system collects not only the heavy abrasive particles but also the removed paint, scale and other waste matter thereby preventing any contaminants from being introduced into the atmosphere.
