I bought this because I liked the idea of it suctioning up the solution on the backstroke. That part works okay, but there are some issues with this design. First, it does not work well on uneven floors. Additionally, during my second use, the solution was not dispensing properly. It was only dispensing on one of the 5 scrubbers. I took it apart and discovered that the solution dispenses out of five holes in front and above of the scrubbers that are so tiny only a paper clip can fit in them to unclog them. This piece is a clear thin plastic rectangular part that has no way of being opened to be cleaned. Terrible design flaw. You shouldn't have to dismantle and clean numerous parts of a floor cleaner after each use in order for it to not be useless.
