The automatic function and design of the product is excellent. However, I would have liked the sensing function to be a bit more intuitive. It doesn’t always sweep after my cat is done. Seems to do it on a regular times scheduled instead.

But note that the crystals are not for every cat. My cat likes to bury his “business” the smell is gone. The crystals can’t do that for him. So he still goes back to the box with clumping litter. We tried taking that away and he didn’t seem happy. So instead, we’re trying out clumping litter in the Scoopfree tray, and it seems to be working better for him!
