Are there floor sanders that can only use specific grits? I ask this because my contractor says that he cannot remove the swirl marks from my newly installed oak floor because his machine does not fit the smaller grit of 100 or 120. If this is the case then I will tell him to get the needed machine. But it just doesn't sound right to me. Please enlighten. Thanks!

He is probably hogwashing you. Your response is the right one: if your machine really can't do it, get one that will.
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.
