Came across this product at the green living show. It uses the suction from its vacuum to attach a miniature chamber that has the sandblasting nozzle and a light source. The sand that is used for this sandblaster is recycled crushed glass.It is very mobile and the posses is safely isolated. It is called the Tornado ACS.
