ABSTRACT:
A vacuum cleaner, which has a cleaning attachment through which dirt and dust are drawn, includes a lighting device that illuminates a surface to be cleaned. The lighting device includes a bulb in a groove that is formed at the cleaning attachment's front, thus horizontally illuminating the surface. Preferably, the bulb is a halogen lamp which is of predetermined length. The groove includes a plurality of air holes so that outside air can flow into the groove. A filter is provided in the air holes to prevent dust and dirt from getting into the groove. The lighting device may be detachably mounted on the cleaning attachment, and includes a case and a bulb installed in the case for illumination. The case includes a plurality of locking pieces that securely fit into a slit formed on the cleaning attachment so that the lighting device is connected to the cleaning attachment.
