Abstract: The disclosed apparatus and method relate to a cleaning nozzle which, in multiple embodiments, is rotated in a circle or in an ellipse, being one nozzle in one embodiment and multiple nozzles in alternate embodiments so that the surface of a pipeline can be clean with high pressure water or other fluids. Furthermore, the rotating nozzle is supported in a carriage in one embodiment which encircles and travels along a pipeline. The carriage is supported by drive wheels which cooperate with separate drive motors and a control circuit to assure that the carriage remains upright. Multiple rotating nozzles are supported in the carriage to clean adjacent portions of the pipeline. Alternate embodiments are shown for cleaning a horizontal surface with a hand pushed or motorized version, and another version is disclosed supported on a moveable boom, thereby enabling cleaning of an upstanding vertical surface such as the hull of a ship.
