THE CLOTH CLEANING DEVICE (30) INCLUDES AN ARM (22) MOVABLE IN A PLANE PARALLEL TO THE POLISHING CLOTH (12A) BETWEEN A FIRST POSITION ABOVE THE POLISHING CLOTH (12A) AND A SECOND POSITION OUTSIDE OF THE POLISHING CLOTH (12A). A JET NOZZLE (31) IS ATTACHED TO THE ARM (22) AND DIRECTS HIGH PRESSURE WATER (31A) TOWARD THE POLISHING CLOTH (12A). AN ENCLOSING MEMBER (40) ENCLOSES THE JET NOZZLE (31) SO AS TO PREVENT THE HIGH PRESSURE WATER (31A), WHICH HAS BEEN DIRECTED OUT FROM THE JET NOZZLE (31), FROM SCATTERING. THE JET NOZZLE (31) IS ORIENTED TOWARD THE CENTER ROLLER (14) AND THE HIGH PRESSURE WATER (31A) IS DIRECTED TOWARD THE PART OF THE POLISHING CLOTH (12A) IN THE VICINITY OF THE CENTER ROLLER (14) WHEN THE ARM (22) MOVES THE JET NOZZLE (31) CLOSE TO THE CENTER ROLLER (14).
