ABSTRACT:
The present invention relates to an upright vacuum cleaner. An upright vacuum cleaner according to the present invention includes a main body for housing a suction power generating device for sucking air and a filtering device for filtering out foreign substances contained in the sucked air. A suction nozzle is pivotably connected to a lower portion of the main body for sucking the air containing the foreign substances and then guiding the sucked air into the main body. A handle is installed at the top of the main body and is designed to be gripped by a user in use. The potentiometer, or some other device for controlling the electric current applied to the suction power generating device, is installed at one side surface of the handle. The potentiometer allows the user to control a suction power level and on/off operations of the vacuum cleaner by means of a sliding manipulation. Further, the potentiometer is preferably installed at a front surface of the handle.
