The CT22 (and all the Festool Extractors) will do things that other brands will not. I remember when I first got the CT22 and hocked it up to a Bosh handheld planer.... well all of the sudden the chips were coming out the planer. When we checked the bag was full and so was the hose, but the CT22 still had full power.
I and my business partner felt stupid for not checking....but DANG we were impressed that it could take it. Now we check the bag more.
The result of our [doh] moment lead us to buy more Festool product because it is engineered so well.
Cheers,
Steve
