Abstract: A wireless cleaning apparatus uses electrical energy to produce calories. Steam is generated with a view to carrying out a cleaning operation by spraying steam. The steam generator includes a water tank, a heater of the water in order to produce steam, and an extractor for the steam produced heater of the steam includes storage for calories generated, prior to the cleaning operation, by electrical connections for producing heat that can be reversibly connected to an electric power supply includes a solid body, which is traversed by at least one channel or similar, which links the water tank to the means for extracting steam, and through which the water travels.

Abstract: A suction device sucks air and liquid from a planar surface, and the scraper blade active portion moves on a surface. The active portion is in the form of a single blade, made from a flexible or semi-rigid material, intended to be moved in one direction against the planar surface. There is an internal cavity connected to a mechanism for sucking air and liquid. At a distal portion of the blade and behind the ridge to be moved on the surface, two walls together form an angle and meet at the ridge. A first wall is presented first towards the surface to be scraped during a scraping operation having, alongside and close to the ridge, a plurality of holes opening into the cavity.

Abstract: The device for heating liquid generates steam, receives a fluid in liquid form at its inlet, and ejects the fluid heated up or in gaseous form at its outlet. The device includes a heater positioned inside a sleeve having a longitudinal axis. There is a scraper that fits onto the heater to scrape it the heater in case of movement along the longitudinal axis. A stopper fits snugly between the heater and the sleeve in order to stopper the passage. The scraper, the stopper, and a spring are configured so that an increase in pressure causes the scraper and the stopper to move along the longitudinal axis so that the stopper is shifted to a point where space between the heater and the sleeve allows fluid to pass, and a reduction in pressure causes a shift in the opposite direction by the spring.
