摘要： The invention relates to a method for controlling the operational mode of a cleaning device, in particular a high pressure cleaning device, wherein a pump (12) transports cleaning fluid by means of a pressure line (18) to a closeable injection nozzle. A signal transmitter (26) is coupled to the pressure line, which produces control signals according to the pressure in the pressure line. The aim of the invention is to improve said method in such a manner that the cleaning device can be controlled in a constructively simple and reliable manner by the injection nozzle. According to the invention, a first control signal is provided by the signal transmitter by closing the injection nozzle and a second control signal is also provided by the signal transmitter by subsequently re-opening the injection nozzle, and the operational mode of the cleaning device is controlled according to the duration of the time interval between both control signals. The invention also relates to a cleaning device, in particular a high pressure cleaning device which is used to carry out said method.

摘要： The invention relates to a vacuum cleaner having a dirt collection container which has a suction inlet and is flow-connected to at least one suction unit via at least one filter and at least one suction extraction line, and having at least one external air inlet which issues into the suction extraction line downstream of the filter and can be closed by means of at least one closing valve, wherein the closing valve has a moveable valve body which is acted on by a spring-elastic return device with a closing force and, in the closed position, additionally by a magnetic holding means with a magnetic holding force. In order to develop the vacuum cleaner in such a way that it permits particularly effective cleaning of the filter, the invention proposes that the magnetic holding means has a solenoid which can be acted on by a field current in order to close the closing valve, and that the valve body can be continuously moved from the closed position, via the open position, back to the closed position in the event of the field current being interrupted, wherein the switch-off time of the field current is matched to the movement time of the valve body.
