The app has not worked for me for close to a year. The Whisker support has given me the same line in all this time. "Try logging out and restarting your phone".The robot thought it was 100% full for a month. I had to manually reset it every time it was used. Now, it just says 80% full no matter whether it is empty or full. It gets stuck so often that my cat started pooping on the floor to avoid using it. I bought a neakasa open top - no problems

So far, so good. A very expensive way to avoid cleaning the litter, but if you have health issues and don't want to scoop all the time and want a contained system, this is a great choice. The kitten took to it immediately and you get reminders/status of the use on your phone app. I clean, wipe down and fill the litter line weekly. Easy to set up. Hope it lasts.

Love it, easy installation and my cats like it too

OMG. I love this item. It is a bit pricey but well worth the cost. It works like a dream and has literally changed my life. I now only have to worry about litter box changes once a week. It also eliminates all the smell from the litter box. In addition, it weighs your cat. My cat loves the litter box as well as the litter box is always clean.

So great in every way!! Wished we would have ordered sooner!!!
