REALLY need help choosing a Vacuum!! What vacuum do you have?

The best thing to do is look at the ratings online. Go to any website where they sell the one you saw on craigslist and see if anyone rated it and what they said. I have never used a canister vacuum so I can't give you an opinion regarding that. But anytime I buy something I look it up on different websites to get a good idea of the reviews. Good luck!
