Abstract
Disclosed herein is an upright vacuum cleaner with a swing brush. The upright vacuum cleaner comprises an upright cleaner body having a suction nozzle, a drive unit mounted in the cleaner body for moving the cleaner body forward or rearward, a grip unit slidably mounted to the upper end of the cleaner body, the grip unit having a sensor for sensing a sliding direction of the grip unit, a control unit for controlling the drive unit to be operated, such that the cleaner body is moved forward or rearward, based on information sensed by the sensor, a movement converting unit for converting a rotating movement of the drive unit to an angular reciprocating movement, and a swing brush connected to the movement converting unit for performing the angular reciprocating movement. The swing brush is mounted in a suction nozzle of the cleaner body while being in contact with the floor.
