Polaris 480 - New Model?

[yellowbellied]

I'm looking for a pressure cleaner and have looked around the web for the Polaris models. My question is that a lot of stores list the Polaris 380 for sale, yet only a few list the Polaris 480 for sale. Even Polaris' home page doesn't list the 480 under their product line. Is the 480 a new model?

Is this newer and better than the 3900? I'm just wondering if it indeed is a newer version, why did they change the numbering?
