For example if you have a shallow nick or small scratch on your hardwood floor you may be able to buff it out by hand without refinishing the entire floor.

Unlike sanding which requires tackling the entire floor you can buff only small areas of your floor if needed.
When we sand hardwood floors with a belt sander we also have to use an edge sanding machine because a belt sanding machine can only get so close to the edges of the room.
On more even grained wood like maple the difference is a lot less noticeable provided the sanding was accomplished correctly.
An edge sanding machine allows us to sand right up to the walls and get in small tight places like corners and closets.
You can avoid this dilemma by screening and re coating a procedure that refurbishes the old finish without.
