I have a Litter-Robot 2 that is probably 5 years old - maybe more. It worked reliably for 2 cats at a time for most of those years - a very busy litter box. Never a problem - had to replace the nylon spacers year ago and the motor about the same time. Finally, one button on the circuit board gave out and much to my surprise the replacement circuit bard prices was reasonably low and the actual labor to replace it was was so simple and only took a minute to do. Now as good as new - again. Thank you for an excellent product and available parts and documentation.
