There was a thread started about the steam mops not long ago:

Personally, I think I am going to go with Shark Steam Mop. Mainly because I already have a shark steamer that I love. It has survived being dropped, kicked, tripped over, etc. I figure if the steam mop is half as tough as the steamer then that's my best route!
