Abstract:
1. An upright vacuum cleaner with a swing brush, comprising: a drive unit; a grip unit having a sensor that senses a sliding direction; a control unit that controls a rotating direction of the drive unit based on the sliding direction sensed by the sensor; and a movement converting unit that converts a rotating movement of the drive unit to an angular reciprocating movement, the movement converting unit being eccentrically connected to a cam shaft, which is connected to a swing brush via a link, to convert the rotating movement of the drive unit to the angular reciprocating movement, wherein the movement converting unit comprises: a belt wound around one end of the drive unit; the cam shaft being rotatably mounted in a cleaner body such that the belt is wound around the cam shaft; a cam pin eccentrically formed at the outside surface of the cam shaft; a link having one end hingedly connected to the cam pin; an angular moving pin to which the other end of the link is hingedly connected; and an angular rotating shaft inserted through the swing brush, the angular moving pin being formed at the outside surface of the angular rotating shaft.
