<p>A cleaning device (1) is disclosed, comprising a water duct having an inlet end and an outlet end, a cavity-producing element (8, 9) arranged at least partly within the water duct to perform a rotational and/or reciprocating high-speed motion for creation of cavities in water flowing through the water duct from its inlet end to its outlet end, and a nozzle (4) arranged for discharging the water from the cleaning device including the cavities formed therein by the cavity-producing element. Furthermore, a method is disclosed for cleaning and/or disinfecting a surface, said method comprising the steps of producing cavities within a flow of water by performing a rotational and/or reciprocating high-speed motion of a cavity-producing element (8, 9) within a water duct through which the water flows, and discharging the water including the cavities formed therein from the water duct onto the surface to be cleaned.</p> |
