ABSTRACT:
A surface cleaning apparatus utilizing abrasive projected at high velocity against the surface being treated. The apparatus defines an opening in an enclosure through which abrasive is propelled in a high velocity stream or blast to impact against the surface. A pathway in communication with the opening receives and directs rebounded, spent abrasive to a collection bin. A rotating brush within the boundary of the opening of the enclosure and the kinetic energy of the abrasive are used to direct the spent abrasive in the pathway. A recycling apparatus is integrated within other elements in the enclosure to collect spent abrasive rebounded in pathway for return to the high velocity blast stream.
