This thing is an absolute POS
I’ve spent so much more time manually resetting sensors and troubleshooting that it’s become way more work than just having a plain old litter box. Not to mention that none of the other features that were advertised (like tracking weight or how many times my cat went in) work. My cat has weighed anywhere between 6-11 pounds according to the robot and that was even after I bought an extra tray to make it compatible with carpet (which of course they don’t tell you before buying). Save your time and money - ABSOLUTELY NOT WORTH IT!!!
