ABSTRACT:
Disclosed is a dual mode vacuum cleaner which can be used as both a canister mode cleaner and an upright mode cleaner. The cleaner can be easily converted from the canister mode to the upright mode or vice versa by simple handling. The cleaner has a body section including a pair of wheels, a dirt-collecting section for sucking air containing dirt, and a coupler assembly for detachably coupling the body section to the dirt-collecting section. In the cleaner, the conversion of the operating modes is achieved in the interior of the coupler assembly by the interaction of elements, so that elements do not protrude out of the coupler assembly, thereby giving the cleaner an improved external appearance. The coupler assembly has a firm internal structure so that the life span of the coupler assembly will be lengthened and its durability will improve.
