Abstract: The present invention relates to a vacuum cleaner. More specifically, the vacuum cleaner comprises: a cleaner body disposed at a position away from the ground; moving wheels rotatably mounted on both sides of the cleaner body and rotatably supporting the cleaner body; a dust container mounted on a front surface of the cleaner body in front of the moving wheel and collecting dust to be sucked; and a suction hose connected to the front surface of the cleaner body and sucking dust, wherein the cleaner body has a center of gravity thereof located behind a vertical extension line of a center of rotation of the moving wheels, and a rear end of the cleaner body becomes closer to the ground when the traveling of the vacuum cleaner is stopped.
