This self-propelled record cleaner can run on the disc record around the turntable spindle while brushing or cleaning dusts off from the disc record when the battery-operated motor unit is in operation. Some of components of the record cleaners are mounted in a casing at a position where they can be supported above a non-grooved area of the disc record.
