Abstract
A self-propelled record cleaner comprising a cleaning brush, a drive wheel, and a battery-operated motor unit for driving both of the cleaning brush and the drive wheel in the opposite directions with respect to each other. The self-propelled record cleaner has a bearing hole adapted to receive a turntable spindle when the record cleaner is placed on a disc record mounted on the turntable. 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.
