  • the surface cleaning head according to the invention has a supply line which can be connected to a supply line, for example to the spray lance of a high-pressure cleaning device. Via the supply line, both the at least one cleaning nozzle and the jet nozzle can be supplied under pressure cleaning fluid.
  • the supply line thus serves the common supply of cleaning liquid for the at least one cleaning nozzle and for the jet nozzle. This facilitates the handling of the surface cleaning head, since the user must connect, for example, the spray lance of the high-pressure cleaning device only to the supply line, then both the at least one cleaning nozzle and the jet nozzle are in flow communication with the high-pressure cleaner.

  • the surface cleaning head has a suction nozzle, which is positionable in alignment with the jet nozzle and at a distance therefrom, wherein the jet nozzle-side inlet region of the suction nozzle is arranged in the housing.
  • the suction nozzle absorbs the cleaning liquid spattered by the jet nozzle, whereby, according to the known Venturi principle, a suction flow directed into the suction nozzle is formed in the intermediate space between the jet nozzle and the inlet region of the suction nozzle. Since the inlet region of the suction nozzle is arranged in the housing of the surface cleaning head, thus liquid from the interior of the housing can be sucked directly into the suction nozzle. This allows a particularly effective extraction of cleaning fluid and cleaned dirt from the surface to be cleaned. The aspirated liquid and dirt can be removed via the suction port.
  • the arrangement of the inlet region of the suction nozzle at a distance from the jet nozzle has the additional advantage that over the entire circumference of the inlet region of the suction nozzle, a suction flow can be generated, so that liquid from all directions can be supplied to the suction nozzle. This enhances the achievable suction effect.

  • At least two cover elements are used, which are each movable between a cover position and a release position back and forth.
  • the cover elements in the covering position are positioned so that they completely cover the passage in their entirety. This ensures that no liquid can escape through the passage, as long as the suction nozzle is detached from the housing.
  • the at least one cover element is conveniently movable against the action of a restoring force from the covering position into the release position.
  • the restoring force ensures that the at least one cover element, starting from the release position, automatically assumes its covering position, provided that the restoring force does not counteract any holding force.
  • a holding force can for example be exerted by the suction nozzle when it is connected to the housing.
  • restoring force is preferably a spring force is used.

  • a valve device in particular a shut-off valve, can be used, with the aid of which the flow connection between the supply line and the jet nozzle can be selectively manufactured and interrupted. This gives the user the opportunity to produce and interrupt the loading of the jet nozzle with pressurized cleaning liquid as needed. He can choose whether he wants to suck the sprayed by means of the cleaning nozzles with pressurized cleaning liquid surface or not. If suction is desired, it can provide the flow connection between the feed line and the jet nozzle by means of the valve device. If a suction is not desired, it can interrupt the flow connection.
