I also used that Bosch hose with a Ridgid vac and it does work well. Then I got a CT26, so I put a Festool 36mm end on the Bosch hose and use it sometimes with my routers and my TS55. The Bosch hose is 35mm but has a 27mm hose end on it. The Festool 36mm end fits it perfectly so you can still use it if you upgrade to a CT at some point in the future.
