I love this router, but the DC needs to be re-engineered IMHO. For one, it is a process to remove and attach.
Second, performance overall is poor. Dados and grooves ok, but routing an edge profile or rabbet it is actually quite poor in my experience (that is collecting with a Festool extractor wide open).
The shroud also obstructs the view of the bit.
I know this isn't the answer you want, but if I were very concerned about DC I would spring for a Festool. DC on several of their other tools I have is quite superior and I would expect their routers to be the same.
