Wow, hooked this up with my Fein shop vac and takes the mud off the wall right now. A little heavy but I choke up on the handle. I'm a weak old man. You robust men would have no trouble with the weight of it.
I used this machine to sand the ceiling after the removal of the popcorn style ceiling and not only did it do a great job smoothing the ceiling but it minimized the amount of dust. I highly recommend it.
Sands very well. Finding replacement disks with the right hole pattern is difficult, so we just cut holes in the right spots. Suction isn't great, we hooked It to a shop vac and that worked decent!
