Vacuuming Easier

I was looking at new vacuums at the store the other day. I don't 'need' a new vacuum but I want one. I vacuum almost daily, sometimes more than once a day with the birds I have and would like a vacuum that doesn't use bags. I like the new ones that have the canisters you simply remove and empty. I also like many of the newer models that come with vacuum dusters, and other cool attachments. I will probably buy a new model online though because you can almost always find a much better selection than you can in stores.
