I like my Eureka! steam mop. It gets the water hot enough to sanitize and doesn't leave puddles of water on the floor, either. It also had a long enough cord that I don't have to constantly unplug and re-plug it in. It is easy to use, light weight, efficient, and I can use an old dishtowel if I didn't want to buy extra pads (which it comes with 2, but you can buy extras for like $10).
And it isn't crazy expensive.... I think it was like $70?
