Abstract: A rotary nozzle assembly has a hollow nozzle body fastened to a high pressure hose, a tubular shaft rotatably carried in the hollow nozzle body, and a head member fastened to the tubular shaft. The head member has a rounded nozzle head portion and a threaded tubular portion and a central blind bore concentric with the central axis of the tubular shaft. The rounded nozzle head portion has a first lateral port passing from the central blind bore through a side of the rounded nozzle head portion at an offset from the central blind bore. This causes an unbalanced motion of the nozzle assembly on the high pressure hose while the tubular shaft rotates with the head member within the hollow nozzle body. This causes the rotary nozzle assembly, when inserted within a pipe, to follow an orbital path around the inside of the pipe.
