Floor Sanders vs grits
There is a difference between belt sanders(a belt turning, with the grit on the outside of the belt), disc sanders (a spinning disc), and random orbital sanders (a vibrating rectangle plate). Belt sanders and disc sanders tend to strip floors better, whereas random orbital sanders tend to create a smoother, finished surface and do not remove finish/wood as efficiently/quickly. But all kinds can use rough or fine grit sandpaper.
