Fence
Most Accessories (optional – sold separately or in bundle)
Ensure proper placement
Your Litter-Robot comes fully assembled and ready to use. Get started by following the steps below.
- If possible, place Litter-Robot in the same location as the old litter box (at least during transition).
- Make sure the unit is on a firm, level surface in a cool, dry location.
- If the unit is placed on carpet or uneven flooring, you will need to use our Carpet Tray accessory to improve the accuracy of weight readings.
- Locate the unit near a power outlet. Ensure the unit isn’t pushed against a wall or into a corner.
- Place litter mats or rugs in front of the unit.
Add clumping litter
Litter-Robot’s litter sifting system requires clumping litter. Note: Translucent or white-colored litter (most often seen in crystal litter) may impact the litter level and Drawer Full Indicator (DFI) accuracy.
What not to use
DO NOT use litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets. Read our best litter for Litter-Robot guide for more info.
Don’t overfill
Fill the globe through the opening until the litter is slightly below the raised fill line when spread flat (about 8-10 lbs by weight or 1 gal by volume). Be careful not to overfill the globe.
Plug it in
Plug the small end of the power supply into the socket on the back of the base. Then plug the AC/DC adapter into a wall outlet. Locate and press the Power button. Litter-Robot will display a solid blue light indicating it is ready for use.
Clean cycle
We recommend leaving the Litter-Robot OFF and operating in "semi-automatic" mode for best results when acclimating your cat. When you see your kitty has used the Litter-Robot, turn it ON and press the Cycle button to perform a Clean cycle. Once it finishes (2 minutes), turn the power OFF. This way, your kitty is safe while they get accustomed to the Litter-Robot—and you don't have to scoop the litter box!
Onboarding
Download the Whisker app
Download the Whisker app and follow the onboarding instructions.
Screens may vary as app gets updated.
Empty the waste drawer when indicated
Empty the waste drawer when indicated by the app or the flashing blue light on the control panel. How often you empty the waste drawer depends on the number and size of your cats. For two average-sized cats, twice per week is typical. For a single cat, once per week is usually sufficient.
We recommend doing a basic Globe cleaning every 1-3 months and a deep cleaning at least every 3 months (depending on how many kitties you have). More frequent deep cleanings may be necessary, depending on use. Refer to our Deep Cleaning Instructions for more details.
To empty the waste drawer, simply pull out the waste drawer, gather the edges of the liner bag, and dispose. To install a new liner or trash bag, wrap the opening over the perimeter of the waste drawer. Push the remainder of the bag into the bottom of the waste drawer.
Add litter as needed
How often you add litter depends on how many cats use Litter-Robot and how frequently they use it. Litter-Robot uses litter very efficiently since the patented sifting mechanism only removes the clumps. We recommend checking the litter level each time you empty the waste drawer. If the litter is below the raised MAX fill line inside the globe, add just enough litter to meet the line.
