Litter-robot 2 automatic litter box (Mt Pleasant PA)

I have two to give away. Both work but the 3 lights on the control panel blink after a cleaning rotation which means the units won’t rotate again unless you unplug and plug the units back in. Litter-robot still sells parts for these if you want to try to figure out what the issue is. You can use them if you don’t mind unplugging and plugging back in after every use. These are about 15 years old. I have been happy with them up to now. Replaced with Litterrobot 4 for over double what I originally paid for each of these ☹️
