Holy cow, Batman! No dust gets out of the router with the CT36 attached.
I've done a bunch of routing with the CT36 where is was sitting on top of the work piece. no outside edges. One hose attached to the top hose connector. Virtually no dust got out.
Just finished an edge routing task 18mmx18mm rabbet on the edge of a workbench top to breadboard the ends, using the edge guide. 27mm hose attached to the top hose connector. Mistake - pretty darn messy.
Did the same edge routing task using the edge guide with 27mm hose attached to the top hose connector -and- 36mm hose connected to the edge guide hose connector. Both hoses were connected to the splitter on my CT36. Virtually no dust got out.
For someone who does a lot of woodworking inside on cold Colorado days, it's awesome. My router table has good dust collection, but it's not big enough to handle 1.5" thick 2'x6' benchtop. This opens up new possibilities for routing inside.
I'm totally impressed with the quality of the Festool design on this one.
