A control system for controlling a cleaning apparatus used for cleaning a steam generator includes a valve manifold which is controlled by a control console to direct a pressurized fluid to either a jetting outlet or a flushing outlet of the cleaning apparatus associated with the steam generator. The control console also controls a motor controller which defines the incremental distance that the jetting outlet is moved within the steam generator to clean different portions of the steam generator. The motor controller is remotely controllable from a platform control device so that the position of the jetting outlet can be changed by a person located on or near the steam generator during initial alignment and limit switch positioning. The control console also controls an evacuation circuit which extracts the fluid pumped into the steam generator and the sludge or other substances loosened therefrom. The control console still further controls the suction valves of a pump which provides the pressurized fluid so that the pressure can be extinguished upon either manual command or an automatically detected condition of the valves in the valve manifold. The pressure from the pump can also be extinguished by a remote controller functioning through the control console.
