    • A vacuum cleaner convertible between a hand-held vacuum and a stick-type vacuum including a housing having a rondure first end and narrowing to a generally oblate, low profile nozzle at a second end, defining an opening in fluid communication with an interior of the housing. A releasably extensible dirt cup is slidably disposed within the opening in the second end and adapted to move between a retracted position within the housing and an extended position from said housing. The free end of the dirt cup is adapted to detachably retain a floor cleaning tool having a pivoting cleaning head for use on floors or other surfaces to be cleaned. The housing contains means for drawing high velocity air into the elongate dirt cup through the floor cleaning tool and/or free end of the elongate dirt cup so as to entrain dirt and debris and capture it within the dirt cup. The dirt cup is cleaned by withdrawing it from the end of the nozzle and removing the spun-bonded filter assembly before pouring the dirt cup contents into a separate container. The low profile housing, together with the extensible dirt cup and detachable floor cleaning tool, easily adapts to a variety of cleaning needs while simultaneously providing a lightweight and ergonomically balanced cleaning tool.
