Abstract

A beach or other surface cleaning method and apparatus is disclosed, wherein low density debris, particularly oil and tar residues, are removed for subsequent separation and disposal. The apparatus employs hydraulic principles to float the debris from the surface, propel the floated debris into a scoop, and lift the floated debris into a receiving trough for subsequent separation. Water employed to provide the hydraulic actions may be recirculated for continuous reuse.
