Good answer from Jimmy.
The only thing I might add is that if you don't have experience using a floor sander, you might want to think of hiring a professional. These floor sanders can make the job much easier or because of their power, can make the job harder. Once you put a gouge in the hardwood, its very difficult to fix.
Have fun.
Guess I need to learn how to use this new board.
