Abstract

A dust collecting direction switching portion is provided at a wall at the back of the main body of an upright type vacuum cleaner. The dust collecting switching portion having a switch valve is branched into three directions. The branch in the first direction forms a duct for allowing a coupling hose to be fitted to a suction opening directed toward a floor surface, the branch in the second direction forms a rib communicating with a dust collecting portion inside the vacuum cleaner, and the branch in the third direction forms a rib allowing a hose to collect dust at a relatively narrow space between pieces of furniture. In operation, in response to an operation of a knob related to the switch valve, the switch valve switches one of the first and third direction ducts in association with the operation to communicate with the rib in the second direction.
