The steam cleaning device contains a steam cleaning head with several steam pressure chambers connected to a steam generator, as well as suction regions connected to a vacuum source. The suction regions are constantly supplied with fresh air from a fresh air chamber connected to the outer surroundings of the cleaning head, in order to improve transport of the steam/water/dirt/air mixture to a backward vacuum lock in the steam cleaning head. Suction slits around the periphery of the steam cleaning head ensure completely stripe-free cleaning of, for example, window surfaces. The steam cleaning head can be part of an automatic cleaning machine used for cleaning windows and skyscraper facades.
