摘要： The invention relates to a vacuum cleaner with a dirt collection tank which has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one extraction line, and with at least one external air inlet which opens into the extraction line downstream of the at least one filter and can be closed by means of at least one closing valve, wherein the at least one closing valve has a valve member which can be moved back and forth between a closing position and an open position, wherein it is acted upon permanently by a closing spring with a closing force and in the closing position, in addition, by a magnetic holding device with a magnetic holding force. In order to develop the vacuum cleaner further in such a manner that it makes a particularly effective cleaning of the at least one filter possible, it is suggested in accordance with the invention that the magnetic holding device comprise an electromagnet with a magnetic core and a coil which can be acted upon with current for the purpose of closing the closing valve, wherein at least one electrical component, which takes up at least some of the energy stored in the coil when the current acting on the coil ceases, is connected in parallel to the coil.

摘要： The invention relates to a method for operating a floor cleaning system having a central suction station with which there is associated a self-propelled and self-steering suction appliance, dirt being picked up from a floor surface that is to be cleaned by means of the suction appliance and being transferred into a dirt collection vessel of the suction appliance, and the suction station having a suction unit, and the dirt collection vessel being sucked out by means of the suction unit. To refine the method in such a manner that the levels of noise produced by the floor cleaning system can be reduced, it is proposed, according to the invention, that the suction unit is optionally operated with a maximum suction power or a reduced suction power. The invention also proposes a floor cleaning system for carrying out the method.

摘要： The invention relates to a method for controlling the operating mode of a cleaner, in particular, a high-pressure cleaner, wherein a pump delivers cleaning fluid via a pressure line to a closable spray nozzle, a signal transducer which provides control signals as a function of the pressure in the pressure line being coupled with the pressure line. To further develop the method so that the cleaner can be reliably controlled in a constructionally simple manner from the spray nozzle, it is proposed, in accordance with the invention, that a first control signal be provided by the signal transducer by closing the spray nozzle, and a second control signal be provided by the signal transducer by subsequently opening the spray nozzle again, and that the operating mode of the cleaner be controlled as a function of the duration of the time interval between the two control signals. A cleaner, in particular, a high-pressure cleaner, for performing the method is also proposed.
