    Abstract: A device for removing and cleaning asbestos containing material from a surface is disclosd. The device has a housing which is moved in a path to clear a swath of asbestos-containing material from a surface. A plurality of knives are positioned on an open face of the housing to make a plurality of incisions in the asbestos-containing material layer as the housing is moved along the surface. A scraping blade trailing the knives scrapes the asbestos-containing material from between the incisions. A sheet of water from a pressurized source is sprayed onto the scraped surface at an oblique angle to wash residual asbestos-containing material from the surface. The liquid spray and asbestos-containing material is aspirated together by a vacuum source connected to the housing, and the mixture of liquid and asbestos-containing material is removed in a separating receptacle.
