It took me a while to get used to using this vacuum as an upright because of the good turning radius, i found it to be a bit awkward.  Once you get used to it, it is fine.  I do prefer to used the canister as makes it easy to switch to the hose and attachments.  I have two dogs and am amazed how well it picks up dog hair - the pet attachment is great for furniture and dog beds!

Pros: Very efficient vacuum.
Cons: i wish the canister had a place for all of the attachments instead of just two.
