  • 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 do I need to add litter to the Litter-Robot?

    The Litter-Robot uses litter very efficiently since the patented sifting system only removes the clumps. We recommend checking the litter level against the raised fill line (on the black rubber liner of the globe) each time you empty the waste drawer, which is about once per week for a single cat or twice for multiple cats. Be careful not to overfill the globe.

  • How often do I need to replace the Litter-Robot waste drawer liner?

    Replace the waste drawer liner whenever you need to empty the waste drawer. How often you empty the waste drawer depends on the number and size of your cats.

  • How often should I replace the Litter-Robot carbon filter?

    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.
