I got this with the hopes of not having to scoop my cats litter box every day/every couple of days, and it surpassed my expectations. This thing works SO WELL! It is very easy to get the dirty litter out and you just replace the litter as needed. I love how it’s easy to use with just a couple of buttons. it does come with an instruction manual that is easy to use and set up. If you’re looking for a non messy, electric, self cleaning litter box then this is for you!
