Hoover WindTunnel. Have always had Hoovers and have always liked them --- I like the WindTunnel best though because there are no bags to buy. Tried an Oreck for 10 days and took it back as I simply could NOT push it on a couple of my carpets (deep pile). Forget the Dyson - those things weigh a ton. For getting into tight places and under beds/ couches I also have a little Dirt Devil RoomMate (again, no bags to buy) that is super lightweight and does a fine job.
