Abstract (en)
A water cleaner machine comprising at least two motors (M1, M2) each activating a respective pump (P1, P2), the pumps being connected in parallel to a water supply line and leading a common dispensing conduit comprising a high-pressure lance activated by a trigger; the machine comprises a single switch (2) having a manual activation which can be positioned in a first position in which both the motors (M1, M2) are disconnected from an electric power source (figure 1), in a second position in which only one motor (M1) is connected to the electric power source (figure 2) and in a third position in which both the motors (M1, M2) are connected to an electric power source (1); a normally-closed pressure switch (5) is placed on a delivery conduit of one of the pumps (P1, P2), which pressure switch (5) is adapted to open when the pressure exceeds a calibration value.
