This is literally a set it, and forget it, until it's time to swap trays. I like that the litter is lightly scented so there are no odors. I love not having to scoop the litter box anymore. Cleanup is a breeze. you simply remove the tray cover it, and dispose of it. The trays are easy to replace, and my cat seems very happy with this litter box. The directions are clear, and very easy to understand.
