  • the vacuum cleaner has a mains socket to which a power cord provided with a power cord of the power tool can be connected.
  • a suction tool generating power tool such as a saw unit, a milling unit or a drilling unit. If the operating state of the power tool is changed, for example, by switching on or off, an incipient current flow or a falling current flow at the mains socket can be detected in the vacuum cleaner. This allows, depending on the operating state change, a suction unit of the vacuum cleaner to be switched on or off as required and to suck off a suction hose connected to the power tool suction hose of the vacuum cleaner.
  • Such a vacuum cleaner comprising a device of the type mentioned, is for example in the DE 20 2007 018 176 U1 described.
  • the above-described device of a vacuum cleaner can not be used even if the power tool while having a power cord, but the power plug can not be connected to the mains socket of the vacuum cleaner. This is possible, for example, if the power cord does not have the length required for this purpose or if it should be routed through a danger zone in which no cables may be laid.
  • the JP 2004-195565 A describes a vacuum cleaner according to the preamble of claim 1.
  • the object of the present invention is to provide a vacuum cleaner and a method which is more versatile.
  • the vacuum cleaner comprises a device for detecting a change in operating state of a power tool having a transmitting device with at least one sensor element, coupled thereto a test member and a test element coupled to the transmitting element and a receiving device with a receiving member and a coupled thereto switching element, said at least a sensor element with the Operating state of the power tool associated measured variable detected and a sensor signal can be provided by the test member on the basis of the sensor signal is determined and the transmission member in the presence of a change in operating state the receiver member contact state change information is transmitted, and wherein the switching element is operable in the present state change information.

  • the transmitting device comprises a fastening device for fixing on the power tool. Fixed on the power tool, the transmitter can not be lost when working with it. Furthermore, it is arranged so close to the power tool that a change in operating state of the power tool can be reliably detected.
  • the transmitting device can be permanently or detachably connected to the power tool, for example by means of an adhesive film or a Velcro tape.
  • the use of a Velcro tape is in practice of particular advantage, because it is thereby possible to attach the transmitting device to different power tools, if they each comprise a Velcro.
