@Melanie make sure to fill the Litter-Robot properly. There should be a guide line inside the globe, do not fill it over or the excess litter will be dumped into the drawer.

What keeps the port doors closed? Is there a magnet or is it the spring? The port door keeps dropping open when the unit is in the ready position. I thought it was a broken spring that had rusted out, so I changed the spring provided by you. Everything worked fine after the first rotation, but then the port door started dropping open again. If I manually close the door, it pops open again after a few seconds. Thereâs no debris blocking the door, and I donât have a lip extender.
@Jsn Thereâs a spring in the back of the globe keeping the door closed. It seems thereâs a confusion, since we do not provide springs for the globes, maybe it was purchased from another company. It seems like the installation of your new spring has been done incorrectly. The door should stay close with the spring. The tension of the spring is pushing on the door, closing it by the pressure.

Mine wonât turn on. It worked fine a few days ago and today I noticed it was starting to smell. When I checked it, I realized it had not been cycling and the lights are not on. I unplugged it and plugged it back in, tried a different outlet, and checked the circuit breaker.
@Robyn The problem you are experiencing is usually caused by the circuit board. If itâs ~3 years old, corrosion in the barrel jack can also be the cause. If itâs been purchased with us, we would suggest you to contact our support center. If not, we would suggest you to purchase a new board.

My LItterRobot recently came out of storage (about 5 months of non use â cleaned, etc, before being put away). When I turn it on, it goes straight to the yellow light. After a bit, all three lights start blinking. Before putting it in storage, it was having issues that I hadnât had time to fix â not rotating unless I started it manually, and then having issues completing a cycle (it often wouldnât go far enough to dump the littler, or if it did go far enough, the globe would get stuck. I could get it to rotate again by lifting the globe and pushing the gear a bit). Now the gear doesnât move at all if I try to trigger it. I checked the circuit board and it looks clean. I also verified everything else above (though I canât tell if the switch is âclickingâ when I press on the safety line. Any idea if this is motor or electrical problem, or both?
@Betsy, the issue youâre describing is mostly caused by the motor, if itâs been purchased with us, we suggest that you contact our support center, if you have not purchased it with us and it is no longer under warranty we suggest that you replace the motor.

My litter robot just stopped turning on. I checked all the steps above and it all looks good. I googled elsewhere and people are suggesting the power port is faulty! Help 
@Sharon, it can either be the power supply, circuit board or the power jack. To verify the power supply you can refer to the Litter-Robot II Advance Troubleshooting guide. If the power supply is working than we would suggest to start by replacing the power jack first. If you have purchase your litter-robot with us you can contact our support center.

Hi, our Litter Robot is not cycling. It starts then stops almost immediately most of the time. Sometimes it will cycle for longer periods before stopping. I have to turn off/on about 10-15 times to get it to complete. I have checked safety wire, bottom cat sensor, gear for stuck debris, and cat sensor for appropriate height/activation.
@Ian The problem you are experiencing is usually caused by the motor. It can be caused by worn out gears.

@Mathieu Our litter robot is under warranty. Can a new motor be sent out if I send the defective one to you?
@Ian Please contact us via our Support Center (https://www.robotshop.com/en/support/ticket/submit/) with your order information. Our support team will verify what can be done.

Having issues with the Litter Robot 2, When cycling it gets as far as getting the litter behind the grate and then goes back without dumping the âremainsâ is there something I can adjust to fix this? where is the sensor located?
@Ilan We suggest you to verify the Advanced Troubleshooting guide to verify the hall effect sensor : https://www.robotshop.com/blog/en/?p=15579

Washed my LR2, thought I was careful about not getting the electronics in the base wet. Plugged it in and nothing, not lights and no motion. Probably the circuit board?
@HD It can be caused by the circuit board or the power jack. Since you have washed your robot, it can possibly be caused by one of these. You can find both parts on our website: https://www.robotshop.com/en/litter-robot-replacement-parts.html

Our Litter Robot is awesome but has recently developed a problem. After our cat exits when it does the initial rotation it gets just to the dumping point and the barrel lifts and skips several times then goes into the return rotation. Itâs very loud and I imagine damaging. Suggestions please. Thanks!
@Gail, it sound like you are having a problem with the sensor harness. On the sensor harness there is a hall effect sensor that detect magnets in the globe, if the globe is not stopping where it should than either the sensor on the sensor harness is not positioned correctly or that it is defective. Here take a look at the Litter-Robot II Advanced Troubleshooting Guide

We replaced the power jack and circuit board earlier this year (itâs about 3 years old). However, now all three lights flash and nothing happens. What could our problem be? Thanks!
