I had the original litter genie. It is GREAT! Except with three cats, the refills were used up very quickly and were getting hard to find. I read that the jumbo refills fit into the standard container so bought a bunch. They don’t fit my model. So I bought the jumbo model. Really dislike it. It is hard to change the refill and you have to touch the dirty Shute to replace it. It also doesn’t hold as much poo. I was able to go a week with three cats and not have to change the bag. Now it is only a few days. WHY DID THEY CHANGE IT?!?!
