ABSTRACT:
Cleaning underlying surfaces, especially irregular surfaces, such as shake roofs, grooved pavements or ramps, and the like. Mobile apparatus under the guidance of an operator brushes the underlying surface and sprays water or other cleaning liquid onto it in a rotating pattern as the operator traverses the apparatus and, thus, the cleaning locus relative to the supporting surface. A "compass point" wheel arrangement enables the apparatus to be positioned with one wheel off the edge of the supporting surface to clean over the edge while maintaining three-point stability, whereas temporary removal of a wheel enables close approach to clean an intersection of the underlying supporting surface and an adjoining wall or other adjacent upright surface.
