  • the high-pressure cleaning device comprises a pump and a motor driving the pump.
  • Cleaning fluid to be pressurized can be delivered to the pump through a pump inlet and the cleaning fluid pressurized from the pump can be delivered through a pump outlet.
  • Different discharge units can be brought into fluid connection with the pump outlet, so that the pressurized cleaning liquid can be directed onto a surface to be cleaned by means of the discharge unit which is in fluid connection with the pump outlet.
  • High-pressure cleaning systems of this type are used for cleaning a wide variety of surfaces, for example for cleaning floor surfaces, building facades and vehicles.
  • different discharge units are used.
  • the type of cleaning for example a rough cleaning, an abrasive cleaning or a foam cleaning, also influences the choice of the optimal discharge unit, that with the pump outlet of the high-pressure cleaning device should be brought into fluid connection in order to achieve the best possible cleaning result.
  • the discharge units differ from one another by their discharge characteristics, for example by a different outlet pressure of the cleaning liquid, a different jet shape, or also by the addition of a cleaning chemical which is added to the cleaning liquid.
