This is a handy thing to have. Keeps from having to hand mop. This robot has 3 different pads, one for dry sweeping before wet mopping and another pad for damp sweeping and another for wet mopping. Its very easy to insert pads. Its a great concept but it doesnt clean stuck on stuff. It does a great job on the floor where there isnt a pile of dried goop. I had 2 piles of dried on icecream onthe floor and it didnt touch them. The different pads for the different cleaning levels smell absolutely wonderful. It doesn't hold much water but it doesnt take much. It decides how much water to use based on the pad that is inserted. Best part - you dont have to touch the dirty pads. Just push a button and the pad is ejected into the trash. If I used it often I would not have to hand mop at all. It is so nice to always have a clean floor.
