The Best-Rated Self-Cleaning Litter Box

The Litter-Robot 3 features an expansive litter chamber and larger, upward-facing entryway that gives it an open-air feel, making it much more inviting and comfortable for large cats. The self-adjusting weight sensor can easily detect both small and larger cats (cats must weigh at least 5 pounds). As with all Litter-Robot units, the litter is automatically sifted after each use and waste is deposited into a convenient drawer, all while using less litter and reducing litter spilling and tracking.

Frequently Asked Questions

  1. Do you ship to PO Boxes?
    No, we cannot ship to PO Boxes.
  2. Can kittens use the Litter-Robot 3?
    It depends how much your kitten weighs. The Litter-Robot senses the weight of your cat to know when it enters and exits the globe, which triggers the countdown timer and cleaning cycle.

    Kittens and small cats that weigh less than 5 pounds may not be heavy enough to trigger the cat sensor. Until they weigh enough, we recommend using your Litter-Robot in "semi-automatic" mode to keep your cat safe and relieve you from litter box scooping.

    For "semi-automatic" mode, leave the Litter-Robot switched off or unplugged. When you see your cat has used it, wait about 7 minutes for the waste to clump, then turn it on/plug it in. The Litter-Robot will automatically perform a clean cycle (which takes about 2 ½ minutes), then turn it off/unplug it again. Continue this supervised, semi-automatic mode until your kittens have gained sufficient weight to activate the cat sensor.
  3. Will my cat actually go inside the globe?
    Cats are generally curious and tend to investigate new things. Those already familiar with a covered litter box may be quicker to investigate the Litter-Robot.

    We recommend placing the Litter-Robot where the old litter box used to be, especially if your cat is fearful of new things. You can remove the old litter box or leave it next to the Litter-Robot for a short time. Then, take a cup of litter from the old box and put it in the globe of the Litter-Robot. The scent will be familiar, and your cat should be inclined to check it out. Once your cat ventures inside and feels the litter under his paws, he'll know what to do! Check out Acclimating Your Cat for more tips and tricks.
  4. Does the Litter-Robot have a weight limit?
    No, the Litter-Robot does not have a weight limit. However, your cat must weigh at least 5 pounds to trigger the cat sensor.

    Size and weight often have little to do with whether a cat will adopt the Litter-Robot or not. When we describe which Litter-Robot model is best for cats of a certain size, our recommendation is based on the size of the globe (litter bed area and height of internal space) and the size of the entryway.

    Our definition of a small cat is 5-10 pounds; medium cat is 10-15 pounds; large cat is 15-20 pounds; and extra large cat is any cat that weighs more than 20 pounds. Again, the Litter-Robot does not have an upper weight limit, so whether or not the Litter-Robot will be comfortable for a large or fat cat is up to the individual. As long as the cat can enter the globe and turn around inside it comfortably, it doesn't matter how much it weighs. The Litter-Robot 3 was made with larger cats in mind; it has a larger entryway and expanded litter bed area to accommodate larger cats.
  5. Does the Litter-Robot require special litter?
    The Litter-Robot works well with almost any clumping or scoopable litter. Litter beads and crystals that are small enough to pass through the screen will also work. Alternative, plant-based litters may also work, but these tend to form looser clumps that can cause condensation in the waste drawer. When using a plant-based litter, we recommend emptying the waste drawer and cleaning more frequently.

    The Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose clumping, newspaper-based, or wood-based pellets. You'll find these incompatible litters create a muddy mess and interfere with the sifting process.

    Feline Pine is not compatible with the Litter-Robot. The large pellet size does not sift well. It builds up on the screen, causing clean pellets to spill into the waste drawer during the cleaning cycle.

    We suggest Litterbox.com all-natural clumping litter.
  6. Will the Litter-Robot eliminate all litter box odor?
    No, the Litter-Robot will not eliminate all litter box odor. However, because waste is promptly removed and contained in the base, typical litter box odor will be reduced significantly. Additionally, a large carbon filter located in the front of the waste drawer absorbs odors and moisture to discourage mold growth (a major culprit of that telltale litter box smell). The amount of odor control the Litter-Robot will provide depends on the amount of odor created—by how many cats use it, what type of litter you use, and your cats' diets, among other things.

    Of course, the more often you empty the waste drawer, the less opportunity there is for odor to escape. That said, if you empty the waste drawer and notice the Litter-Robot is still a source of unpleasant odors, we recommend changing out the bed of litter completely, deep cleaning the Litter-Robot twice per year, and replacing the carbon filter and seal strips as needed.

    It is also worth noting that scented litters are generally not as effective at absorbing odors as unscented litter. Instead, we recommend an unscented, odor-trapping, natural litter like Litterbox.com all-natural clumping litter.
