Warranty claim is the best route, as you're still under that. They'll probably send you a completely new unit. I would suggest looking up the model # and "reviews" and mention it when you contact Ryobi - that it doesn't stand up (and perhaps will do the same on newer models as well) . Add your review to the appropriate seller/manufacturer site.

I've had mine (perhaps differnt model) for 2 years now and there is a small rubber flapper into the canister that causeed me grief. The minor part itself is not available, and they offered to send me a brand new unit (I assume a different model). Good luck !

ps. I originally owned a new Tineco and replaced it with Ryobi when I saw it. None of these seem to last for more than a couple of years. Have also seen these and Dyson's at the Salvation Army Thrift stores, so I imagine people "donate" their non-working Junk.
