Oreck XL2
I hate this vacuum. I bought the Oreck XL2 five years ago and if I hadn't paid $500 for it, I would have gotten rid of it a long time ago.
It does an alright job picking up dirt, but there are no attachments to get behind stuff or under stuff and dirt leaks out around the bag and is a mess to change as well as being difficult to do. It seems cheaply made and crappy.
The small hand held one I got "free" with it also does alright picking up dirt, but is very awkward to use. I will never buy another Oreck!
