Abstract

A method of cleaning surfaces so as to remove dirt, buildup, paint, asbestos, coating materials, or any other buildup or layer from the surface using a high fluid pressure cleaning for removing coatings and buildup from hard, often porous, and generally unpermeable surfaces such as brick, concrete, limestone, masonry, stone, asphalt, etc. Specifically, the method of surface cleaning involves high pressure water dispensation, or non-caustic chemical and then high pressure water dispensation via a number of different sized, shaped, and usage housings that include at least one rotating jet for applying the high pressure cleaning water that thereafter vacuumed out of the housing after cleaning by a high suction vacuum where the housing includes one or more rows of annular or peripheral sealing means such as brushes, rubber seals, rubber wipers, or other similar flexible yet sealing instruments. The housing is moved along the surface to be cleaned which in the case of a building is vertically up and down a track, while also being moved horizontally from a cleaned path to a non-cleaned but to be cleaned path.
