<p>#CMT# #/CMT# The vacuum cleaner (1) has a suction fan (24) for creating vacuum in a suction tube (12), where an end of the tube is provided with a nozzle (10). A detector detects the presence of the nozzle. A housing comprises an electronic control unit (25) for activating the suction fan in two operating modes when the nozzle is detected and not detected, respectively, where the modes respectively correspond to the supply of minimum and maximum electric power to the suction fan. The detector comprises a radio frequency identification (RFID) reader (26) for detecting an RFID tag (16) placed on the nozzle. #CMT#USE : #/CMT# Vacuum cleaner for cleaning smooth floor and carpet. #CMT#ADVANTAGE : #/CMT# The detector and the control unit adjust the power of the vacuum cleaner according to the type of nozzle of the vacuum cleaner and/or according to the utilization mode of the vacuum cleaner in an automatic manner, thus reducing the electric energy consumed by the vacuum cleaner if the presence of the nozzle is detected, and ensuring the supply of maximum power to the suction fan if the nozzle is not detected, for allowing a user to utilize a stick only for picking bulky and difficultly accessible wastes. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a vacuum cleaner. 1 : Vacuum cleaner 10 : Nozzle 12 : Suction tube 16 : RFID tag 24 : Suction fan 25 : Electronic control unit 26 : RFID reader.</p> |
