I have white stone flooring in my home and as you can image it's rather hard to keep clean with 3 humans and 3 dogs. I was tired of breaking my back from using a scrub brush and mop twice a day on my stone floor just to keep it looking some what clean.. I'm SO happy I bought the Scooba, It is well well worth the money esp if you have harder flooring to keep clean. this little buddy does everything, it leaves only a faint trail of water after it's cleaned a spot, but then goes over it again to buff and dry (you can just step on a towel and dry it up.) Very easy to use, very effective! I was surprised with how well it cleans and how easy it is to clean it after using. I'm a very satisfied customer.
