We love our litter robot! It does exactly what it claims to do. There is no scooping required. We have 2 – 6 month old kittens. With the robot we change the bag 2 time per week. Any bag will work in the machine. I use kroger brand 13 gallon bags. You might be able to go smaller. You could possibly use shopping bags. So easy to use. At first our kittens had no issue with using it, but they often jumped in it while it was spinning since they were so nosey. After a few days of that they stopped doing that and now use it w/o any problems. It also cuts down on the cat stink. And I was doubtful about the claim of needing less litter, but I will tell you it is true. I would estimate that I now use 25 – 30% of what I used to use.
Always room to improve. Here are some ways litter-robot could be better. 1. have a fill line on the litter so when I am pouring it in I know when to stop pouring. I know there is a fill line, but that isn’t applicable while you are pouring. (if you overfill it just goes to the discard bag on the first cycle.) 2. Have a larger storage bag section. I’d love to only empty it once a week, but now that may seem like laziness! 3. Wish I could afford 4. I wish there was an alarm to hear instead of all lights flashing if there is an error
Overall – worth the buy.
