Hi AprilLove, The Auto Roll Pad has a lenghtly delay between the time the pet wets the pad and it rolls to a dry pad, I had shortened the delay for the video. In my testing the pet was long gone before the pad was advanced. Also the Roll Pads are perforated and will tear, and their is a small guard on the wet roll end that was not installed on the version in the video.
As to the poop, my pets have never pooped and peed in the same place. For what ever reason Jazz picked a different area in the house when we didn't take her outside, but it was always in the same area and pretty much the same times of day so generally speaking it was not hard to find, easy to pickup and dispose of with out a mess. If Jazz had pooped on the pad and the sheet rolled after becoming wet, the poop would be pulled to edge of the pad and the roll guard would stop the poop from being rolled up.
Also on my later design, I have changed the drive motor on the pad roller and it moves vary slow, 5 revolutions per min.
