Abstract
A vacuum cleaner having a suction path switching unit is provided that includes a cleaner body having a body frame; a suction inlet body hinged to the body frame; an extension pipe assembly having a hose and an extension pipe connected in fluid communication with the hose; and a suction path switching unit disposed on the body frame. The suction path switching unit has a switching duct, at least a portion of which is elastically arranged on a suction path to be displaceable on the suction path. As the extension pipe is fixed on or separated from the body frame, the switching duct is selectively displaced to a first position of opening a first suction path flowing from the suction inlet body to the dust collecting unit or a second position of opening a second suction path flowing from the extension pipe to the dust collecting unit.
