This product does not get dirt off the floors. The little brushes barely graze the floor surface. That however is not my biggest complaint. The amount of water it leaves behind is terrible. It does not suck anything off of the floor, and leaves puddles of water. I am following the directions, I have installed properly. Now I just have a big bulky floor cleaner, that I paid a lot of money for, that does absolutely NOTHING but dump water on my floors for me to wipe up.
