Can't remember why I thought I needed this sander sitter. You have to set the sander down in it perfectly or it spins off the bench. If using a variable speed on highest setting the whole thing will "walk" off the bench if you leave it running more than a few seconds. First time my sander hit the floor I was a little more than upset. The whole mech is too light. As for the cleaning aspect, with the new stearite disks you can get, here on Amazon and from suppliers like Klingspor, you are hard pressed to ever load em up anyway. It's another one of those "good ideas" that just doesn't transfer from concept to actual use very well. If you just really have to have one, let me know, I'll send ya mine for the cost of postage. Can't recommend this one.
