ABSTRACT:
An upright vacuum cleaner having a filter bag housing assembly comprised of a fabric or otherwise flexible and air permeable bag housing resiliently supported at its bottom end relative to the operator handle such that the bag housing is always in tension and is prevented from twisting about the axis of the operator handle. The bag housing assembly includes rigid upper and lower frame members thereby maintaining the assembly in a prescribed geometric shape. The lower frame member which defines the bottom of the bag housing includes a pair of laterally disposed elongated track members telescopically disposed within respective guide track members fixed to the handle and resiliently biased relative to the respective guide track member to thereby maintain the bag housing in tension and provide lateral stability to the bag housing at the same time.
