The present invention discloses a novel device to clean the air-bearing surfaces of various magnetic thin-film heads used in magnetic hard disk drives and glide heads used in hard disk manufacturing to detect surface asperities. This device couples the conventional cleaning method of solvent or dry wiping on cloth and vacuum cleaning. The device is composed of a piece of porous weaved cloth sitting on top of the flat surface of a perforated chamber connected to vacuum. When the slider or magnetic head slides over the cloth, debris and particles are removed by the wiping action and by vacuum suction. If organic contamination on the ABS surface is suspected, a solvent such as isopropyl alcohol or actetone could be sprayed onto the cloth to further improve cleaning. The present invention has the following advantages over the conventional wipe cleaning: 1. it truly eliminates particles due to the suction provided by vacuum, conventional wiping only displaces them unless the cloth is changed every time. 2. when solvent is used, solvent vapor emission is minimized due to continuous suction. 3. the suction holds the slider or head more tightly on the cloth surface, providing more intimate contact and thus more effective wipe cleaning.
