I purchased this Mighty Mite to replace one I had over 15 years.  The only things on this new one that even comes close in comparrison are the power of the motor - which is good, and the extension wands.  The hose is so poor quality that it folded and cut off the air flow on my first use!! the housing feels like it will crack if you bump it into something, the wheels are not much better.  The motor makes for good suction, that is really the only positive I can give on this unit.  The old gray model I had since the late 80's was wonderful! I replaced that one with an Oreck, but wanted to go back to something with wheels on the floor for touch-ups, baseboards, overhead cleaning, etc.
