Yes, I use one but not for ROS sanding discs. I use it to clean my 48” stationary belt sander, my 9” disk sander, my oscillating drum sander and my 1” belt sander. Also my flex sander. The ROS disks never clog as it is permanently hooked up to my shop vac and Dust Deputy. The cleaning block works great for all the sanders and last forever. I had it for as long as I can remember and it’s still usable.
