This is an awesome easy to use self cleaning litter box. Getting set up took minutes. I love the counter at the top of the box so you can see how many times a day your cat is actually using the litter box. It cleans very well. I have mine in my bedroom. The light at the top is blue and doesn’t bother us at all during the night. When it cleans there is about a 15-20 minute delay to make sure your cat isn’t in the litter. The sound doesn’t affect us at all during the night and I love seeing a clean litter box every single day. I love everything about this machine and so does my cat. He had no problem whatsoever changing over.
