  • Why have the Litter-Robot 2 Classic and Bubble been discontinued?

    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.

  • How often should I replace carbon filters?

    For optimal odor absorption, we recommend changing the carbon filter every three months, but replacement frequency is up to you and your cats' usage patterns. If you use scented litter, we recommend changing the filter more often as it will also absorb the litter scent.
