Litter-Robot: Getting Started with your Litter-Robot III Open Air

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 2.25kg. Cats must be 2.25kg or more to activate the cat sensor., both to automatically clean and also, to activate important safety features
  • Always place the Litter-Robot on a firm, level surface. Avoid deep carpet, which may affect the cat sensor sensitivity.
  • Always turn off the Litter-Robot and unplug the power supply from the back of the base, before removing the bonnet.
  • Never force your cat into the Litter-Robot.
  • Never put anything in the Litter-Robot 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 Litter-Robot
  • Never remove the globe or bonnet while the globe 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 Litter-Robot is on a firm, level surface. Avoid soft, uneven, or unstable flooring.
  • Keep the Litter-Robot indoors in a cool, dry location. Reduce exposure to high temperature and humidity.
  • Locate the Litter-Robot near a power outlet. Ensure the Litter-Robot 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 Litter-Robot. Do not place mats partially under. 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 suitable clumping clay type of litter. If you are currently using a non-clumping litter, you will need to switch to a clumping type BEFORE introducing the Litter-Robot, to make transition more successful. 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. and confusion, and you may have toileting issues.

  • Fill the globe through the opening with suitable clumping clay litter until it is just under the raised fill line when spread flat (about 4.5-5kg by weight).
  • 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, with low dust, fast clumping and preferably carbon or activated charcoal addative for odour assistance. Litter beads and crystals that are small enough to pass through the screen will also work , and some non-clay litters (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  (jack) into the socket on the back of the Base. Then plug the AC/DC adapter into a wall outlet and turn on the power point.


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  (soiled litter) from the clean litter,
  3. depositing the soiled clumps 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 by the blue flashing light, and add litter to the globe at the same time to replace the used litter. DO NOT add litter to the globe unless you are emptying the waste drawer, as the cat sensor is at the base of the Litter-Robot and adds drawer and globe contents together.


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.  Generally, peeing is testing, and pooping is transitioned. See the tips below 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 familiar 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 favorite treat neat the entry but not inside the globe.
  • FAMILIAR SCENTS: Add a scoop of litter from the old litter box to the Litter-Robot to provide a familiar scent for your cat. Cycle it through if it is soiled, to introduce the scent better.
  • 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, to encourage them to transition to the cleaner Robot. If you feel you need to scoop the old box, put it into the Robot and cycle.
  • MAKE THE OLD LITTER BOX LESS ATTRACTIVE: If your cats are not using the Litter-Robot within a few days, stop cleaning the manual tray and let it go as long as possible without cleaning. Cats prefer a clean litter box and a dirty litter box might persuade them to use the clean Litter-Robot. If you have introduced new litter with the Litter-Robot, you will need to work to transition the litter in both Robot and manual tray, before being able to progress the introduction to the Litter-Robot.
  • 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 flashing 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, lift free of tabs, tie up  and dispose. You can tip any loose litter in the drawer into the bag before tying up. 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. Make sure the bag edges are below the top edge of the waste drawer to avoid false full flashing.
  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. Only top up the litter level when you empty the waste drawer, as the litter in both globe and drawer are weighed by the cat sensor, and additional weight in the globe without emptying the waste drawer can result in cycle issues. Basically, the cat sensor may think your cat is in the Litter-Robot, and will not cycle (slow flashing yellow light fault)each time you empty the waste drawer. Check that the litter level is to the raised line on the liner, or below if you have denser (finer particle) litter. 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.
