Apparatus for cleaning the interior surfaces of large diameter pipe provides a lightweight basic structure that is easily adapted to clean a range of diameters of pipe. The apparatus uses an interlocked drive mechanism to develop axial movement of the device and synchronize the rotary movement of the cleaning nozzles. The rate of movement is adjustable, to accommodate pipe of varying diameters. That way, the cleaning spray covers a swath of pipe surface, with a minimum overlap between passes, with no gaps in the cleaning.
