ABSTRACT A vacuum cleaner (10) is connected to a dust collecting nozzle (14) via a hose (11) provided with a hose handle (12). The vacuum cleaner comprises a suction fan (17), driven by an electric motor (18), and an electric control device (20) for the control and/or setting of the motor speed for different operating modes. The control device (20) is operated by an operating device (21) disposed on the hose handle (12) and being electrically connected to the control device (20) via two coils, coupled to each other, a primary coil (28) of which being disposed in the vacuum cleaner and a secondary coil (26) being disposed in the hose. A conversion device (31, 34, 36, 38), disposed in the vacuum cleaner, is provided to sense and convert the states of a secondary circuit (25, 26), having as a part the secondary coil (26), said states corresponding to different operating modes and being caused by said operating device. The operating device (21) has a design so as to operate, via an intermediate means (23), the secondary circuit (25, 26) to take two separate electrical states. In dependence on the operating mode set by the operating device (21), the intermediate means (23) operates to keep the secondary circuit (25, 26) in one state during a time which is dependent on the operating mode set.
