I have been really pleased with the Black & Decker Dustbuster since my mother purchased it several years ago because it's light enough for me to carry up and down flights of stairs without tiring out, but powerful enough that it goes a long distance until you need more power. The little dustpan nozzle is so flimsy that if you don't hold it just right it'll break off from underneath when using it. I've owned three of these over time. All started to fall apart within 2-3 months.
