The invention relates to a method of control for a device such as a vacuum cleaner or a central vacuum cleaner comprising a central machinery and a pipe or a pipe system connecting the central machinery with a working point. In order to avoid the installation of control conductors connecting the working points with the central machinery, the operation of the central machinery is controlled according to the invention in a wireless manner by means sound or pressure impulses transmitted from the working point to a receiving sensor using the pipe or the pipe system of the device as a transmission channel, whereby for the start-up of the central machinery, sound or pressure impulses are transmitted from the working point; said impulses are detected with an acoustic sensor; and the central machinery is started in response to the detection of the acoustic sensor; and for the stopping of the central machinery, the flow in the pipe system is blocked; the stopping of the flow is detected by means of a flow sensor; and the central machinery is stopped in response to the detection of the flow sensor.
