  • Patent number: 4519113
    Abstract: An upright vacuum cleaner having a tubular push-pull handle of one or more separable sections, this push-pull handle is detachable at its base end from the upright vacuum cleaner and the opposite end of the push-pull handle is connected to the vacuum cleaner's suction power system by means of a flexible hose. When the vacuum cleaner's suction power is supplied to the hose and the push-pull handle is detached at its base end, the push-pull handle now becomes an immediate suction cleaning wand. This invention eliminates the need for a separate flexible hose kit. The housing on this vacuum cleaner is slightly larger than on previous machines. The housing opens up to receive the dust filter which formerly was external.
