Review on Festool 496187 CT 26 Selfclean Filter Bag - Pack of 5 by Chris Martin

So I had about 800 SF drywall jobs. I had a CT 26 which I used extensively for a whole day at work. I have a bag change (or several) in mind that will be necessary over the course of this work. I'm done with all of my drywall, including all the associated sanding work. If I were using the little Nilfisk UZ934, I would have killed a few filter bags. Instead, this bag here does not show that it is still full. I didn't have to slam the car to get the dust out of my pocket. I no longer had to pray for it to work. Why would you use cheaper bags again? They actually require a lot more work!
