Patent number: 10130230Abstract: A surface cleaning machine including at least one cleaning roller, a drive device for rotary driving of the at least one cleaning roller, a wetting device for applying cleaning liquid to the at least one cleaning roller, and a suction unit arrangement for generating a suction stream is provided. The suction unit arrangement is fluidically connected to at least one suction duct and at least one suction nozzle that is associated with the at least one cleaning roller. The wetting device includes at least one pressure-controlled switch that opens a fluid path for cleaning liquid to the at least one cleaning roller and shuts off the fluid path, and the at least one pressure-controlled switch is coupled to the at least one suction duct, wherein a suction stream in the at least one suction duct moves the pressure-controlled switch into the open position and/or maintains the open position.Type: GrantFiled: April 11, 2017Date of Patent: November 20, 2018Assignee: Alfred Kärcher SE & Co. KGInventors: Fabian Moser, Manuel Schulze, Christoph Rufenach, Johanna Buchmann, Andreas Mueller
