I have the H2O mop from the infomercials (I got it at walmart super cheap). I love it. The floor dries super fast, no chemicals and it gets EVERYTHING off. scuff marks, even stickers. Just leave the mop on top of the sticky thing for a few extra seconds to let the steam penetrate, and it comes right off. Cleans the grout in the tiles pretty good too.
I also use it to steam the carpet. It doesn't get off the super-tough-set-in stains, but will remove dirt stains. And it leaves your carpet feeling all fluffy and new.
My only complaint is that the cord is too short, I have to keep finding closer plugs, but no biggie really.
