New question as a follow up. If I get the ETS EC 125, what would be the drawback with using my regular shop vac? Would a hobby woodworker like me even notice the difference from using a variable speed vac? I mean I've only used a Dewalt ROS and Shop vac for the past five years.
Thanks again!
Aside from noise...the singular downside is that the sander might get "sticky" as you get to the finer abrasives if it doesn't have a way to vary the speed/vacuum. The CT extractors (and some other higher-end vacuums) have controls that allow you to vary the suction. You can use a bleeder attachment on the hose if need be to simulate a "speed/vacuum" control, of course, but I never found them to be quite as effective as the electronic control on the front of my CT.
The "sticky" effect can be a little more noticeable with the Festool sanders because of the increased air flow design includingn the center hole. The combination of very fine abrasive being somewhat "smooth" and high vacuum makes for what starts to emulate a "vacuum clamp".
