I have a Festool vacuum, CT22. It is a few years old, but I don't think it has a lot of use. The problem; it will run for about 3 minutes and then shut down, after a few minutes it will run again for another 3 minutes. I removed filters and bag thinking maybe a clog was over heating it, no good. I called Festool, they suggest I replace to motor for $130. Boy, I'm sure getting tried of fixing tools. While I'm ranting about Festool, what is with the electrical cords. If you keep them in the case the cords kink and breaks pretty easily. I know they are easy to chance, but they are not cheap.
