Bests & Worsts Reviews from Amazon

I am disappointed in that the design of this mop means that dirty water flows back into the cleaning water chamber. I thought the whole point was to keep dirty and clean water separate. Note that there are other mopping systems on Amazon where the dirty water is wrung out into the separate chamber. The unit is surprisingly sturdy and well made, but I don't get the point of having separate chambers if the dirty water you wring out is contaminating the clean water.
