I have the Haan Slim & Light Steam Mop and I LOVE it! I bought it 2 months ago when we moved into our new house with wood and tile floors. It heats up in 30 seconds and has a really low profile so it fits under everything. I think it gets the best reviews out of all the steam mops on Amazon. I use it once a week usually in the kitchen, dining, and living room areas and our housekeeper does the whole house with it once a week as well. The Eureka Envirosteamer is a lot more bulky it seems.
