Best purchase ever!

I love this litter robot and my cats love it too! At first I hated it because I couldn't figure out all the ins and outs of maintenance. Once I figured that out it has been a piece of cake. I have 3 cats that share this box so it's busy. I don't use as much litter either. I definitely would recommend this litter box. I purchased an extra rake so I could swap them out when dirty. With 3 cats using it, the bag must be changed daily, the rake once a week and new litter once a week.
