The cleaning wash is sprayed just ahead of the mop so no extra liquid is running everywhere or so asking in the floor. It will take off dry sticky messes from the floor and !makes it quick and easy to clean a floor. It is simple to use. It is easy on the back. Leaves floors clean and shiny. The only problem I have had is that the last sweep sometimes leaves residue where you pick up the mop. Not a big problem. The mop is affordable and coupons are always available on the website to get you started. Refills are not expensive. Using a system like this keeps click flooring from getting to much moisture. Works great on tiles, wood and cushion floors also.
