Abstract
The present disclosure provides a control method for automatically detecting what kind of nozzle is a nozzle mounted on a cleaner by using different starting current profiles. The cleaner may include a suction unit for suctioning dust, and various nozzles which are detachable from the suction unit. The nozzle may include a rotation cleaning unit which is accommodated in the nozzle to clean a surface to be cleaned, and a nozzle driving unit for driving the rotation cleaning unit. The nozzle may exhibit different starting current profiles depending on the number of rotations or reduction ratio of the nozzle driving unit, or whether an auxiliary control unit is included.
