I recently discovered how great a steam mop is and have been recommending them to everyone! I have a shark steam mop. Read more about why it's so great here: http://hubpages.com/hub/eco-friendly-steam-mop-shark-stea...
I have tile floors, but it would be the perfect solution for wood floors because the steam evaporated almost immediately, so you have clean and sanitized floors easily and instantly without the need to go back and dry it!
