So it started off doing a pretty good job with the paw prints but then all of a sudden it just stopped laying down water so I'm guessing it ran out of water but it wasn't smart enough to know that it ran out of water to go back and fill up with water. When it did go back to fill up with water and came back out to start mopping again the area that it missed and left dirty paw prints still is undone with dirty paw prints so it wasn't smart enough to know that it missed those paw prints and go back and clean them. I have a P10 I think it's called Pro or Ultra and then I got a P10 Pro Gen 2 as well and both of those have the rotating round mop heads and I am not sure that I think the cylinder does any better job if anything I'm leaning toward the fact that my round ones are even better than this cylindrical I will reserve judgment for now but I am skeptical. I would have thought a unit that costs more than twice what my P10 cost would do a far superior job and I'm not sure I can say that.
