Apparatus is disclosed wherein a high pressure spray nozzle is inserted into an enclosure or vessel for the purpose of automatically cleaning the interior thereof. The spray nozzle is connected to first and second successive swivel joints mounted in perpendicular to one another such that the nozzle may be rotated about two axes. An automatic external control mechanism is connected to respective rotary actuators which rotate the nozzle around the respective axes. The control mechanism varies and controls the speed and degree of movement of the spray nozzle in both axes and also automatically reverses the rotation of the nozzle in both axes. The control may be set to automatically operate the nozzle in various patterns of coverage and shape.
