I will not buy a DC6000...because I don't need two machines and for that price I don't need better dust collection. I have lived with what I have (DC-3300) for many years BUT for the right price (<$300) I could get intrigued with an upgrade but only if I know exactly what I am buying.
What does more HP do for me if I am spinning the same fan blade. Would I get more CFM and if so how much? Don't make me speculate! Commit the details!.
I thought the response from engineering laid it out: it's the combination of the new impeller and impeller housing that give more CFM.
Given that those new parts all fit inside the old DC3300 shell, it seems to me that when the service parts for the DC6000 become available, it should be possible to buy the new impeller and impeller housing and connect them to the old motor/motor housing and get the increased cfm performance.
Now, before anyone says I'm speculating, we know the new motor housing connects to the old impeller housing (because a new impeller housing isn't part of the upgrade). So the new impeller housing will connect to the old motor housing. Similarly, the new motor connects to the old impeller (since a new impeller isn't part of the upgrade) so the new impeller should connect to the old motor.
