H.W.
My mom bought one of those Shark steam mops off the TV and she actually likes it quite a bit. I've used it many times and think it works fantastically. It really does get sticky and horrible things off the floor very well and doesn't use any chemicals either. It's even easy enough for a kid to use (my 2-year-old will be ecstatic when we finally let him try it out).
When I'm finally in the market for a mop of my own (I just borrow my mom's, since we live in her basement apt), I would definitely consider getting one of those.
