I have one that's 3 1/2 years old. The tools on it have awesome suction but I don't have any suction from the actual vacuum itself. I can clean all my corners and around my baseboards really well but not my carpet.

Dh has taken the whole thing apart and cleaned it twice and I've replaced the HEPA filter and it still won't vacuum the carpet.
I'm ready to buy a new vacuum cleaner but DH insists that my Dyson should be fixable and that it should have lasted longer than that. Meanwhile, My carpets need a really good vacuuming and I don't have anything to do it with unless I do it all with the tool attachments and who wants to do that?
