Suction hose adapted for use with a suction device, in particular a vacuum cleaner or a dust extraction system, comprising a radio receiver for receiving radio signals across a radio link, the suction hose comprising a first end adapted to be connected to a suction opening of the suction device and an opposite second end adapted to be connected to an air outlet of a hand-held electric or pneumatic power tool, and a communication device located at or near the second end of the suction hose, the communication device comprising: - a sensor element for detecting a current operation status of the hand-held electric or pneumatic power tool and for outputting a sensor signal depending on the detected operating status of the power tool, - a radio transmitter for transmitting a radio signal across the radio link, and - a processing device which is in operative connection with the sensor element on the one hand and with the radio transmitter on the other hand and which is adapted to cause the radio transmitter to emit a radio signal depending on a sensor signal received from the sensor element and optionally taking into account further parameters, wherein the communication device is designed to realise only unidirectional communication across the radio link from the radio transmitter of the communication device to the radio receiver of the suction device, characterized in that manually operated switching means are assigned to the communication device, in particular one or more buttons, switches, keys or dials, configured to be manually actuated by a user of the power tool for controlling the suction device, in particular for turning on or off the suction device and/or for increasing or reducing a rotational speed of a motor of the suction device and/or for initiating, terminating or controlling a flushing of one or more filter elements of the suction device by a reverse air flow, via the unidirectional communication across the radio link. - a sensor element for detecting a current operation status of the hand-held electric or pneumatic power tool and for outputting a sensor signal depending on the detected operating status of the power tool, - a radio transmitter for transmitting a radio signal across the radio link, and - a processing device which is in operative connection with the sensor element on the one hand and with the radio transmitter on the other hand and which is adapted to cause the radio transmitter to emit a radio signal depending on a sensor signal received from the sensor element and optionally taking into account further parameters, wherein the communication device is designed to realise only unidirectional communication across the radio link from the radio transmitter of the communication device to the radio receiver of the suction device, characterized in that manually operated switching means are assigned to the communication device, in particular one or more buttons, switches, keys or dials, configured to be manually actuated by a user of the power tool for controlling the suction device, in particular for turning on or off the suction device and/or for increasing or reducing a rotational speed of a motor of the suction device and/or for initiating, terminating or controlling a flushing of one or more filter elements of the suction device by a reverse air flow, via the unidirectional communication across the radio link.
