A cleaning apparatus for a boiler including a boiler enclosure having a plurality of spaced-apart heat exchange tubes positioned therein comprising a movable support positioned outwardly of the boiler enclosure having a first, elongated hollow pipe extending therefrom which is introduced into the boiler enclosure. A pair of spray arms are mounted on the end of the first pipe and rotate with the pipe to supply high pressure cleaning water onto the tubes so that debris is washed from the heat exchange tubes.
