Litter-Robot II Basic Troubleshooting Guide | RobotShop Community

my litter robot is fouling up. the yellow light comes on when plugged in and then the three lights blink. it used to try to cycle but now didn’t earn do that. any advice besides check the board foe urine?

@tink This issue may caused by a defective power supply. You may to replace the Power Supply. Here!

Our sensor seems to work, the red light comes on. But then it just goes to green without spinning. I can cycle in manually no problem. Thoughts?

@Robyn, The circuit board or the cat sensor will probably have to be replaced.

My Robot is stopping mid cycle and the yellow light in blinking on the bottom.

@Wesley Does the yellow light is blinking rapidly? If so, it’s possible the power supply is defective, we would suggest you to take a look at the voltage of the power supply.

My litter robot sensor no longer works. I’ve tried resetting. The only thing that has changed is that I moved the litter robot to a different room in the house and now the sensor will not work. I can press the cycle button and it works but if I put pressure on the unit the emergency stop will not work. Please advise

@Beverly, we will suggest you to try the followings check ups HERE

I have 2 robots. 1 working great the other was rotating through the dump position and would stop at a random spot after a while. I used parts from the good robot to test the bad robot. The good globe did not fix it, the good circuit board did not fix…so I ordered the wire harness and replaced. Now it is cycling and stopping at the correct dump position, rotates back correctly, but over rotates slightly past the home position and stop and flashes all 3 lights. Did I install something wrong on the wire harness?

@Kelly, You may want to verify if the Position Sensor is on its right place.

Just purchased my Litter Robot III. It works great the majority of the time, but sometimes will stop during the cycle, and the yellow light will blink rapidly. The instructions say this is an indication of a pinch sensor however it is difficult to tell from the illustration how to clear this.

@Laura Shannon You can use the Litter-Robot Open Air: Replacing the Pinch Detect Terminals video to reach the pinch detect terminals and clean them properly. Sometimes, the error appears when the pinch detect terminals are dirty.

When I power on the LR2 the yellow Cycling/In Use light immediately lights. After a few minutes all three lights flash. Repeat every time I power it on. I’ve reseated the cat sensor multiple times, also pulled the sensor out of its home and cycled the button, doesn’t seem to make a difference. Any suggestions?

@Mike,
It seems to be a jammed motor. You can try replacing the motor. You can fin new ones HERE

I have a LR2 that seems to be working fine. It cycles completely at the right speed. The problem is that all the clumps are not being dumped into the waste drawer. Some are but many still remain in the globe even after several cycles. If I had to guess, I’d say there is an issue with the waste ports, although I am getting some clumps in the drawer along with some clean litter.

@Mary Morelly Hi, we suggest you to start a cycle by pressing on the Cycle button and verify the reason why some clumps are still inside the globe. If there’s an issue with the waste ports, we suggest you to verify and clean them accordingly.

I have a litter robot II…the yellow light is stuck. When I unplug it the yellow light stays on when the power comes back on. Any suggestions?

@Aimee Carter, The yellow steady light means that the motor must be jammed in some ways. You will need to verify if the motor is jammed.
Did you buy the robot with us? If so please contact us trough our Support Center under the Domestic department.
You can also find a new motor HERE.
Here is a LINK about how to replace the Litter Robot 2 motor as well

I have a litter robot II… and when it cycles it doesn’t stop at the waste disposal point but just keeps turning. And when does stop it’s upside down. If I then switch it of and pull out the electricity jack and turn it back on a couple of minutes later it returns to normal again. But a day later it does it again. What’s wrong with it? Any suggestions? Because I don’t know which parts I have to replace.

Hi,

From what you are saying, it seems that there is an issue with the Hall Effect Sensor which causes the robot to have difficulty tracking the position of the globe.
We suggest you try replacing the Sensor Harness: RB-ltr-62
