ABSTRACT:
A vacuum floor polisher wherein polishing material is fed by gravity from a tank and dropped onto the floor through the center of a polishing disc which rotates the polishing material on the floor. The floor is polished by the rotating polishing disc and with the polishing material fed, which after polishing is sucked up by the stream of air and recovered into the upper tank. By incorporating adequate cleaner in the polishing material, the floor is polished and the dirt removed by the rotating disc and the polishing material. The dirt adheres to the polishing material. By mixing wax with the polishing material, the waxing is carried out together with the polishing step.
