Yup, I have a Litter Robot 4 and we love it. It saves a ton on little costs, but was a massive upfront cost.
Easier to travel and the litter stay clean, it’s always clean for the cats and they love it. We’re big fans.
Keeping itself clean while we’re gone is such a huge benefit. We have three cats and finding people to care for them used to be a pain in the ass. Now we have the Litter Robot and a couple of automatic feeders so we can leave for days at a time and the cats barely notice we’re gone.
I had no end up trouble with my Litter Robot 3. So much I ended up just throwing the whole thing away.
