A sewer pipe is cleaned of collected solids by providing a water supply hose at a first location on the pipe and by driving a jet nozzle head to a second location along the pipe using jets directed along the pipe. At the second location the head is changed for a second head attached to a cable and is pulled back to the first location by the hose. The nozzle is then pulled back to the second location by pulling the cable while nozzles directed along the pipe toward the second location drive the solids forwardly to the second location for extraction.
