I'd hate to see you destroy a beautiful Walnut floor. Oh maybe not destroy, but take twice the work to fix. Personally speaking, sanding floors is not a DIY project though many will lead you to believe so.
Sorry that's not the answer you wanted to hear.
I don't think that's true. There are sanders you can use that are far easier to use then the pros, belt floor sanders. Varathane used to rent these floor orbital sanders that were about 14-16" square the did a very good job. They were slower then the belt sanders, but were far more forgiving in the, "use" department. Home Depot used to have displays in their stores and rent them. Now they have Rental Stores that do it.
