The method involves setting orientation parts (1-6) on a floor of rooms (R1-R6) independent of a sucking and/or turning device (G). The orientation parts are provided in form of landmarks. The orientation parts transmit room-spreading signals i.e. radio signals, by activation of the orientation parts via a remote controller (7), where the signal comprises an individual identifier that concerns the orientation part. The orientation parts transmit room-limited signals i.e. optical signals, according to confirmation that the sucking-or turning device is moved towards the orientation parts. |
