Litter-Robot II Basic Troubleshooting Guide | RobotShop Community

Hi, the litter robot II does not automatically cycle although the green light is on. If I manually turn on/off the robot, it starts the cycle. Could you please advise?

Hi Jojo,
It seems that the cat sensor will need to be replaced.
Here is a LINK to our website of how to replace the cat sensor.
You may also find the cat sensor HERE.

Litter robot stopped cycling after cat uses. Light stays green.replaced the wire harness and didn’t fix. Red light comes on when I manually click the sensor switch. However doesn’t cycle just returns to green. Pushing the other buttons has no impact on red light. Robot cycles fine if I push the green button. Not sure if a switch issue or the control panel. Did notice that my safety. Switch set up is different than your instructions. Had a black plastic piece that the two black wires were connected to rather than being connected to metal pieces.

Hi Linda,
It seems that you will need to replace the Cat Sensor on your unit.

My litter robot has been having issues lately; now when i switch the power on, no lights even come on half the time, or if they do it is just a solid red light which begins blinking red if it’s left on for an hour or so. It seemed like the motor was struggling more and more - could the motor have burned out? Or do you know what else might be indicated by this behavior?

The red light flashing is caused by an excess of weight or the cat sensor being activated for a too long period of time. We recommend that you verify the cat sensor installation. The motor could also be an issue since there are small gears inside the assembly and they could be damaged.

I inherited a litter robot when I adopted a 10 year old cat from a divorcing couple. It seemed to work perfectly until I changed the litter. When the kitty came he came with a 20 lb bottle of Tidy Cat Glade litter. My housemate brought home a different version of Tidycat litter the Tidycat Lite and now the used clumps of litter just stick to the bottom of the globe. Is this a litter issue or is there something I need to apply to the bootom of the globe to prevent the litter from sticking? Poor kitty he is such a good boy he deserves better. Advise please
what is the best brand of litter for the robot? Or do I need to coat the interior with something if so what? Help pleas.

Hi,
The Litter-Robot has been designed to work with various types of litter, not just the premium clumping clay litters. The sifting screen is suitable for both clumping, scoopable clay litters as well as for alternative litters such as Litter Pearls, Crystals or World’s Best Cat Litter.

Hello, I recently Our have day a replacement circuit board for my LR -2. Everything seems to work fine, except when t goes through a cycle, it’s doesn’t go all the way around. It stops about 60 degrees short of dumping the waste, then spins back clockwise slightly past the rest point then returning to the rest point as it should. I’ve checked all sensors and connections for cleanliness and everything looks good.

We suggest you contact us via the support center since this issue will require further troubleshooting. Try to include pictures of the unit or video of the cycle.

My litter robot has a solid yellow light that stays on. It runs properly other than this light staying on. I’ve tried unplugging it and resetting it.

Hi Kayla,
Please remove the globe and check the black gear connected to the motor. When you press on the black gear with your finger, does it seem loose or free‐spinning? If so, please follow the instructions for tightening the set screw, here: http://litterrobot.kayako.com/Knowledgebase/Article/View/85/41/litter-robot--free-moving-gear-solution

When replacing the globe onto the base, make certain that the track around the outside of the globe is properly aligned into the groove on the base.

My lr2 rotates about 9 holes then sits there and skips. I have been just rotating it one hole when it does this. It will complete its cycle like normal if you move when it skips. How do i fix the skipping?

Hi,
Concerning the issue of the robot cycling on its own, the problem may be caused by a defective motherboard. You can buy a replacement HERE
You can also buy replacement seals so the globe won’t slip anymore HERE

Hello, our litter robot 2 is moving slow recently, so we purchased a motor to replacing the old one. However, once we followed the instruction installed. when turning it on, the yellow light is on steady, i can see the motor have a very brief move and it stop right away. Any idea of what’s going on? Thank you.

@Jessie Make sure that you have plugged the cat sensor and the anti-pinch trigger switch properly. Also, make sure that you have plugged the motor correctly. Green-Red wires together and Brown-White.

Hello, I’ve read through all the posts and seems many are experiencing the same issue as me but different answers are given so I don’t know where to start. When I turn it on, motor will move for a split second and yellow light stays on. After a minute or so the red light will flash. Nothing else happens even if I press the buttons. I checked the sensors and all seems to be fine and not triggered. What part needs replacement? Thanks!

Our robot won’t turn on at all anymore. There was recently a storm that tripped the breakers on the wall where the robot was plugged in. Potentially a surge? Turning the breakers back on every other appliance and outlet is now working without issue but our robot won’t turn on! Devestating! How can I fix I it? Is their a reset button? To clarify plugging it in the unit appears turned off no lights.

@Peter The issue could be caused by either the cat sensor, the anti-pinch sensor being defective or the motor being jammed. You can use a voltmeter and test the switches to verify if they both triggers when pressed down. If they do, then it is possible the motor is the problem.
