Query: First 60 days were great but..........

Bought it in May 2003 to use on hardwood floors and on occasion, oriental rugs. Worked great out of the box. Its lightweight, adjustable, and convenient.Two weeks ago, the on/off switch started to not consistently work. This week, dead...I couldn't recommend buying this product based on my experience unless you want to gamble... It is a great design, but very poorly executed.
