Litter-Robot III Open Air Basic Troubleshooting Guide | RobotShop Community

Hi, my litter robot goes into the counter clockwise cycle, pauses to dump as usual but then continues going counter clockwise. It “jumps” with a loud pop when it does this and does not settle back in the home position-just keeps cycling counter-clockwise.

Hi Laura,

From what we see, it seems like the Hall Effect Sensor will need to be replaced Unless you have disassembled your Globe recently. We suggest you contact us via our support center if you have bought the robot with us and want to proceed with a reparation.

I love the concept of the litter robot but there is one thing I can’t figure out. There is terrible waste odor coming from it. I have 2 cats so I empty it every two days. I emptied the litter Saturday night. And cleaned with vinegar and replaced litter. By Sunday afternoon there was a terrible stench. By today which is Monday it smells rotten. What can I do?

@Mary Ann
Sometimes the Litter-Robot can smell. You may have to change the waste drawer bag more often to solve this problem. Also, perhaps the carbon filter needs to be either washed and rinsed, or changed. It is located inside the handle on the drawer; it pulls out from the inside on the bottom.

You also want to make sure that your cat is turning around all the way inside the globe and not missing outside the globe. If the cat IS turning around in the globe and the carbon filter is okay, you may need to purchase waste bags with an odor shield; these should be available at the local grocery store. Hefty or Glad make them.

There is also a product available called “ammo carb”. It is available at pet stores and can be put in the bottom of the waste bag and in the waste drawer.

Also if you have kittens, this could be a problem since they are young and not fully developed and sometimes it could be the food.

Lastly, if there is a lot of urine in the litter robot from your cat(s), we would recommend adding crystals to the existing litter OR purchasing one with crystals already mixed in. Tidy Cat and Arm & Hammer make such a blend. What they do is absorb the liquid.

I left a comment but I haven’t heard back from you. I was wondering if ammo-carb can be mixed in with the litter. Is it harmful to cats?

@Mary Ann You can certainly use ammo-carb directly in the litter box. Sometimes, customers are having great results with unscented litter, compared to scented litter.

Hey guys, great site. I have the Litter-Robot 3 and it rotates to the empty position and stops fine but then continues in the same direction and stops and the middle light just flashes. If I hit reset = nothing, if I hit cycle it will try and continue in the same direction and either stop or force itself and pop off track or makes terrible noises. I’ve reset it several times, cleaned it etc. I was hoping you had some advice. I figure it needs a anew sensor or switch or something.
Thanks in advance.
-Justin.

@Justin It is possibly due to the AntiPinch sensor, or the hall effect sensor.

My box is not turning on at all.

@Josh Is there any light on the control panel?

Hi, Justin here again, re: June 20 2018. It operates the same without the dome in place and just the bonnet on. It will cycle through, stop @ “empty” then continue in the same direction for a second and a half before it stops and flashes yellow continuously. I’m about to check the Anti Pinch Sensor for good contact. Is there a way to test the hall effect sensor?
Thanks again.

I cleaned the contact terminals on the anti pinch sensor and it is working like brand new.
Great website.

My open air is continually flashing red, we’ve taking it apart and cleaned everything. No amount of resets or anything seems to help. It’s just flashing red. What do we do next?

Hi,

Please check your unit for the following:

  • The litter is above the fill line or in excess of 10lbs.
  • CATS has not been reset after adding weight
  • The waste drawer has too much weight
  • The unit is sitting on an uneven surface ‐ grout lines on tile floor or in a bathtub.
  • The unit is pushed into a corner, against a wall, or furniture
  • Objects are resting or pressing on the unit

The red blinking light indicates CATS (the cat sensor) is detecting excess weight for more than 2 minutes. To test your changes, power the unit off and then on. Allow the unit to complete the start‐up cycle and return Home with a solid blue light. Your unit is operating normally. If it continues to flash, let us know so we can troubleshoot further.

Always press Reset after emptying the waste drawer, adding litter, or moving the unit. You can also turn the unit OFF then ON to ensure the baseline is set properly. When pressing Reset, watch for the blue light to quickly flash one time. This indicates CATS has been successfully reset.

If none of the above solves the issue:

  1. Remove the bonnet.
  2. Remove the globe
  3. Replace the bonnet
  4. Press Cycle (without the globe on the unit)
  5. Allow the motor to run for 5 seconds, at any point, does it stop and flash red? If no, then excess weight needs to be removed from the globe. If yes, (it blinks red), your unit will need to be repaired.

Please respond to this email and let us know the results.

my Litter Robot III will not power on. I’ve checked the plug and it works. I’ve taken it apart and cleaned it, and still no power. Any suggestions?

Hi Jackie,

If you have no lights on the control panel while the Litter-Robot is plugged in, it could be a few issues:

  • The power supply might be defective : if possible please verify it with a voltmeter.
  • If you leave the unit plugged in, is the control panel hot at touch?
  • It could also be the circuit board that is defective.

The pee clumps gets stuck to the rubber. How do I keep this from happening? I’m using Dr. Elsey’s Precious Cat clay clumping litter.

Hi Jenny,

Make sure you fill the globe with litter to the fill line.
If there is not enough litter in the globe, it may result with clumps stuck to the rubber.

Hi, I have a litter robot 3, suddenly it started to stop activating the cat sensor as soon as the night light turns on, the yellow light turns on and flashes, if I turn on the room lights, the night light turns off has it should, and the robots resume normal operations. I now have to keep the Room Lights where the robots are always on so that the robots do their job at night.

@Ronald This is due to the bonnet being defective. You simply need to replace it.
