Abstract
An equipment for suction and high pressure cleaning is described, which comprises at lest one drained liquid collection tank (C), a tank for cleaning water, a vacuum pump (PV) to create and maintain a set degree of vacuum inside the drained liquid collection tank (C ), a pressure pump (PP) that supplies water at high pressure for cleaning and an engine (M) to drive the two pump (PV,PP) where the number of revolutions of at least one of the pumps (PP,PV) is independent from that of the other pump and from that of the engine (M). At least one of the pumps (PP, PV) is connected to the engine (M) by means of variable speed power transmissions (TP, TV), controlled by a logic unit (UL) which maintains the engine (M) at the minimum number of revolutions necessary to supply the energy required by the pumps (PP, PV). <IMAGE>
