Abstract
A portable vacuum cleaning apparatus intended to be carried either on a single shoulder or worn backpack style, wherein the vacuum cleaner has an extensible tube and nozzle arrangement that may be held substantially fully enclosed in the vacuum cleaner case, wherein the hose or wand may be collapsed when not in use to prevent entanglement, or may be incrementally extended and secured in a desired position for use. Additional advantages of the present invention include a suspension arrangement for flexibly suspending the internal components of the vacuum and for providing a moment to counteract the force and movement of the wand.
