I really don't see the wye issue as a problem, I don't see how you would get that much debris to clog the system. The reason I say this is because if you have the system on, and it has enough power to move the air and debris you should be running the DC for long enough after completing the task without even thinking about it. For example, if I'm routing a profile on a board on a router table, after it passes the bit, I am moving the work piece, shutting off router, then shutting off the DC.
