Getting Started with your Litter-Robot 3



Your Litter-Robot 3 ships fully assembled. Follow these steps to get started and refer to the Instruction Manual for more information


First, let’s review some important safety instructions.

  • Always be sure that any cat in your household that might use the Litter-Robot weighs at least 5 pounds. Cats must be 5 pounds or more to activate the sensor.
  • Always place the Litter-Robot on a firm, level surface. Avoid deep carpet, which may affect the unit’s sensitivity.
  • Always unplug the unit before servicing.
  • Never force your cat into the Litter-Robot.
  • Never put anything in the unit other than clumping cat litter.
  • Never sit on or place anything on top of the Litter-Robot.
  • Never wet or submerge the bonnet or base of the machine.
  • Never remove the globe or bonnet while the unit is rotating.
  • And never turn the Litter-Robot on if the globe or bonnet is removed.

Your Litter-Robot comes fully assembled and ready to use. Get started by following the steps below.

  • If possible, place the 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. Avoid soft, uneven, or unstable flooring.
  • Keep the unit indoors in a cool, dry location. Reduce exposure to high temperature and humidity.
  • Locate the unit near a power outlet. Ensure the unit isn’t pushed against a wall or into a corner (must not be touching any walls).
  • Place litter mats or rugs in front of, or completely under, the unit. Do not place mats partially under the unit. Use only low pile (¼ inch) rugs and mats.


When filling the Litter-Robot for the first time, it is best to continue using the brand of litter you were using previously—as long as it is a clumping type of litter. If you are currently using a non-clumping litter, you will need to switch to a clumping type. Please note, your cat will need to adjust to the new litter box, and introducing a new litter at the same time may increase their anxiety.

  • Fill the globe through the opening with clumping litter until it meets the raised fill line when spread flat (about 8-10 pounds by weight or 1 ½ gallons by volume). 
  • Be careful not to overfill the globe.

The Litter-Robot litter sifting system requires clumping litter to work properly. We recommend a high-quality clay-clumping litter. Litter beads and crystals that are small enough to pass through the screen will also work (periodic changing of this type of litter is required).

  • DO NOT use litters that are strictly absorbent, non-clumping, loose-clumping, newspaper-based, or wood-based pellets.

If you are not sure if your current brand of litter is right for the Litter-Robot, contact us at




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. The Litter-Robot will perform an initial Clean Cycle that will last about 2 ½ minutes.


When your cat exits, a timer counts down, allowing litter to clump before a Clean Cycle begins:

  1. As the globe slowly rotates, 
  2. the patented sifting process separates the clumps from the clean litter,
  3. depositing them into a carbon-filtered drawer below. 
  4. The globe returns to the Home position, leaving a clean bed of litter for the next use. 
  5. Empty the waste drawer when indicated and add litter as needed.


Your Litter-Robot is now ready to use; however, we recommend powering the unit off until your cat becomes familiar with the Litter-Robot and begins using it regularly. See the next page for tips on how to introduce your cat to the Litter-Robot.

Most likely, your cat will quickly adapt to the Litter-Robot. Here are some ways to facilitate the transition:

  • LOCATION IS KEY: Place the Litter-Robot in the same location as the current litter box, set it up (make sure you add litter to the globe), and make sure it is turned off. Give your cats a day or two to explore the Litter-Robot. If your cats show no interest, entice them to approach the Litter-Robot by using some catnip or a favourite treat.
  • FAMILIAR SCENTS: Add a scoop of litter from the old litter box to the Litter-Robot to provide a familiar scent for your cat.
  • USE TREATS: Place treats on the step or around the Litter-Robot so your cat associates rewards with the unit.
  • INTRODUCE THE CLEAN CYCLE: Once you notice that your cats have used the Litter-Robot, power the unit on to cycle the unit. Encourage your cats to be present, so they can observe the motion and become familiar with the sound of the Litter-Robot while you are there to reassure them. Turn the unit off again once the cycle is complete (the Litter-Robot should be in the Home position). We recommend that you no longer clean the old litter box once your cats have used the Litter-Robot.
  • MAKE THE OLD LITTER BOX LESS ATTRACTIVE: If your cats are not using the Litter-Robot within a few days, continue using the old brand of litter in the old litter box, and let it go as long as possible without cleaning it. Cats prefer a clean litter box and a dirty litter box might persuade them to use the clean Litter-Robot. Also consider replacing the litter in the Litter-Robot with a litter specifically formulated for litter box training. 
  • SAY GOODBYE TO SCOOPING: Once your cats are consistently using the Litter-Robot, you can turn the unit on and leave it on to operate in automatic mode.



  1. Empty the waste drawer when indicated by the blue light on the control panel. How often you will need to 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. To empty the waste drawer, simply pull out the waste drawer using the handle, and gather the edges of the liner bag and dispose. To install a drawer liner or trash bag in the waste drawer, open the bag and roll down the edge. Push the rolled edge of the bag into the four tabs starting at the back and working your way toward the front of the waste drawer. 
  2. Add litter as needed. Again, how often you will need to add litter depends on how many cats use the Litter-Robot and how frequently they use it. The Litter-Robot uses litter very efficiently since the patented sifting mechanism only removes the clumps. We recommend checking the litter level once per week or each time you empty the waste drawer. Check that the litter meets the raised fill line inside the globe. If litter is below the line, add just enough litter to meet the line. Be careful not to overfill the globe.



Power Button

  • Press and release the Power button to turn the system power on and off.
  • Press and hold the Power button to toggle the night light on and off.

Cycle Button

  • Press and release the Cycle button to start a cleaning cycle.
  • Press and hold the Cycle button to activate the 8-hour sleep mode.

Empty Button

  • Press and release the Empty button to empty the litter into the waste drawer.
  • Press and hold the Empty button to enter the wait time setting mode.

Reset Button

  • Press and release the Reset button to pause any cycle. If pressed while the globe is in the Home position with the blue light on, it will reset the cat sensor.
  • Press and hold the Reset button to activate the control panel lockout.




  • When the blue light is on, the Litter-Robot is in standby mode and ready for use.
  • When the blue light is flashing, the waste drawer is full and should be emptied. After emptying the waste drawer, be sure to press the Reset button to cancel the indicator light.


  • When the yellow light is on, the Litter-Robot is cycling.
  • When the yellow light is flashing once per second, it will mean one of two things: (1) The cycle was interrupted by the cat sensor. If the cat sensor is activated while the unit is cycling, it will stop. Fifteen seconds after your cat has left the globe, the unit will resume cycling. (2) The bonnet has been removed. If the bonnet is removed while the globe is in the Home position or during a cycle, the unit will stop. Five seconds after replacing the bonnet, the unit will resume its previous function.
  • When the yellow light is flashing twice per second, it means the cycle was interrupted by the anti-pinch feature. If the anti-pinch safety feature is activated while cycling, the globe will reverse direction for two seconds, then stop. The yellow light will flash for one minute. Then, the globe will attempt to rotate toward the Home position again.


  • When the red light is on, the cat sensor has been activated and wait time is in process.
  • When the red light is flashing, the cat sensor has faulted. That means the cat sensor has been continuously activated for 2 minutes or more. Either a cat won’t leave the globe, or there is too much weight in the unit caused by overfilling with litter.
