If you want to get down to wood then why don't you just re-finish the floor? Rent a floor sander and all the paint will be gone in very short order - GONE! You also need an edge sander. I can't imagine trying to strip an entire floor - you would need gallons of stripper and days of effort and then you would probably still need to sand the floor b/c you would be left with such a mess. A dresser or chair, yes strip it - but a whole floor?
