Litter-Robot III Open Air Troubleshooting

Litter-Robot III Open Air Troubleshooting

If you’ve been troubleshooting issues with your Automatic Litter-Robot III Open Air to no avail, try this Fresh Restart to eliminate confounding conditions and identify the problem if there is one. This process will help you communicate the issue to our Customer Service team, so you can get your Litter-Robot working again.

Litter-Robot Open Air Fresh Restart

It is important that you carry out this entire process through Step 10, no matter if an earlier step has apparently resolved the issue.

Step 1:  Power Down

Press the power button to turn the unit off, then unplug the power supply from the back of the Base.

Step 2:  Disassemble the Bonnet and Globe

Remove the Bonnet by depressing the side tabs, tilting it backward, then lifting up, and set it aside.

Then remove the Globe and set it aside (you do not have to empty it of litter). We’ve assumed that your Globe was at the Home position with the litter resting on the black liner, but if your Globe wasn’t at the Home position, be careful not to spill litter out of the waste port.

Step 3:  Situate the Base

Ensure the Base is properly situated on firm, level flooring, that it is not pushed against anything (like the wall), and nothing is resting on it. If you have your Litter-Robot on carpeting or flooring with cracks, grout lines in the case of tile, or any other deformity that could result in uneven contact, either relocate the unit, or place a board underneath it. For the Cat Sensor to work accurately and reliably, the Litter-Robot must always be free-standing, meaning it’s not leaning on anything and nothing is leaning on it.

Empty the Waste Drawer (even if it’s not very full).

 Step 4:  Reassemble the Globe

Put the Globe back on the unit in the Home position, ensuring that it is on the track.

If you feel that one side of the Globe is heavier than the other, peer through the screen into the litter pocket (the area where clean litter is held during a cycle). Any weight concealed here could throw off the unit during cycling. Check for stuck litter, especially if you recently cleaned your unit (leftover moisture may have interacted with the litter). If you see debris or suspect there is litter caked behind the screen, you will need to clean the Globe (the screen should not be bent outward to clean behind).

Once aligned on the track, check that the litter level inside the Globe is at or below the raised Fill Line on the black rubber liner when spread flat.

Step 5:  Reassemble the Bonnet and Position the Internal Shield & Key

Replace the Bonnet by first aligning the rear tabs in the Base, then tilting the Bonnet forward, and snapping the side tabs into place. Make sure all four tabs are secured.

At the back of the Globe, rotate the black Key into pocket in the Base.

Step 6:  Double Check

Ensure no part of the unit is pushed against a wall or has anything resting on it.

 Step 7:  Power Up

Plug the power supply back into the Base, and press Power to turn the unit on.

Step 8:  Automatic Reset

The unit should perform an initialization cycle: the Globe will rotate counterclockwise to the Dump position, then rotate clockwise past the Home position to level the litter before returning to the Home position with a solid blue light. The Cat Sensor is automatically reset at the end of each cycle.

Step 9:  Test Cycle

Press Cycle again to test that your unit can complete a cleaning cycle and return to the Home position with a solid blue light. Continue to Step 10.

Step 10:   Manual Cat Sensor Activation

Press on the Globe just above the entrance in a forward and downward direction—just press and release. The blue standby light should turn off and the red light should come on. You’ve activated the Cat Sensor to simulate your cat entering the Globe, then exiting. Allow the Wait Time (3, 7, or 15 minutes—whatever you have your unit set to) to elapse and the cleaning cycle to finish. The Globe should return to the Home position with a solid blue light displayed on the Control Panel; if you get this result, there is no issue with your Litter-Robot.


If, during Steps 9 or 10, the unit does not return Home with a solid blue light, please note the light pattern and position of the Globe. This information will help Customer Service advise you on further troubleshooting, so you can get your Litter-Robot working again!
