Abstract

An automatic wet sanding apparatus is equipped with a suction unit having a suction nozzle that is located under an automatic wet sanding unit in a state where automatic wet sanding is performed and a suction device that generates a suction force for suctioning water through the suction nozzle, so that water having been used for automatic wet sanding can be suctioned through the suction nozzle. This can significantly reduce the amount of water containing sanding dust that flows down a painted surface under the suction nozzle, and thereby reduce the amount of sanding dust that remains on the painted surface after completion of automatic wet sanding. As a result, it is possible to achieve a quality finish on the painted surface while eliminating the need for the troublesome task of wiping off remaining sanding dust.
