A hydraulic remote control device for a high pressure cleaner comprises a flexible hose (2) equipped with a control device (3) for starting and stopping the operation of the controlled apparatus (1) and, for example, a cleaning lance (4). A programming device (5) is also mounted in series with the flexible hose (2) upstream or downstream of the control device (3), as well as a treatment unit (6), permanently raising in a stepwise manner the pressure in the flexible hose (2) by means of a corresponding transducer (7). The treatment unit controls particularly the operation of a motor-pump group (8) feeding the flexible hose (2) with fluid under pressure, as well as the nature and composition of the fed fluid, as a function of the pressure or of the progression of the raised pressure in the flexible hose (2).
