<p>The suction device has a motor (4), a suction connection (5) for a device (6) to be connected with the suction device, a filter and a device socket (8), to which the device is electrically connected. A current- or power sensor (10) detects the current- or power consumption of the device attached to the device socket. The sensor is attached to a processor (12), which delivers a signal for cleaning a filter (2) with consideration to current- or power consumption value.</p> |
