Due to the release of the Litter-Robot 3 and subsequent changes in demand of the Litter-Robot 2 Classic and Bubble, we have discontinued regular production of these models. We will continue to carry component stock for all warranty claims and future out-of-warranty repair requests. Although we cannot guarantee that we will stock replacement parts indefinitely, it is our goal to maintain full service on discontinued products for 10 years. Beyond warranty, you can purchase replacement and reconditioned parts, or you can contact us to schedule repairs or a tune-up.
