K.C.
I bought my Dyson in 2004 or early 2005. It's the purple one (Animal) and it DOESN'T lose suction, just like the commercial says, and we've abused ours...not cleaned the filter every six months as recommended. It's a bagless which is good and bad. Good that we don't have to spend extra money on bags, but it's more work to clean out the canister every other month or so ...which I don't do that frequently and it still sucks up dirt great! They cost a lot but you can buy older models and they should still work as well as the newer models (the Ball version). Good luck!
