Have had my Catgenie now for two years. Have had one issue about a year in which customer service took care of immediately and sent me the little parts to complete. They were awesome and knew exactly what it needed. I use the deep cleaner about three times a year with only one cat using the box. Disinfecting wipes are great to wipe out the surfaces and nooks inside and out.
I can't imagine EVER having another regular litter box again. This thing is so easy.
We moved to another house and I had to hook up next to the washing machine. Piece of cake and works wonderfully. We now have a septic tank, so it is nice to know the granules are septic safe.
