摘要： A convertible vacuum cleaner providing a detachable upright handle permits the vacuum cleaner to be used as an upright cleaner for cleaning rugs, carpets, and the like. A detachable portable hand cleaner handle is also provided which is mounted when the cleaner is to be used as a portable hand cleaner. A resiliently biased, releasable connector is mounted on the filter bag to detachably connect the filter bag to either of the handles. The connector is connected to the upright handle. The connector is resiliently connected to the bag so that the bag remains in proper extended position in all operating positions of the upright handle. A receiver having a socket and a mating blade on the handles permits the two handles to be selectively mounted on the power unit of the cleaner. The portable handle provides a shoulder strap which is retracted into the handle by a reel when not in use and is locked at any selected extended position when the shoulder strap is in use.
