ABSTRACT:
This invention relates to upright vacuum cleaners which have a detachable hand-held vacuum hose as an ascending line. The hand-held vacuum hose is coupled to a hand-held vacuum tube which serves as an extension. The hand-held vacuum tube is thereby designed as a storage housing for the telescoping hand-held vacuum hose.
