I read a ton of reviews and for our almost all wood-floor apartment in Chicago, this thing is AMAZING.  Extremely powerful, yet light to carry.  It can get a bit warm if you aren't changing the bags on a regular basis.  Bags are cheap and easy to order on Amazon.  Best money I spent on a vacuum.  I woudln't pay any more for the unit than I did, but for it's exact price, it's a gem.
