Understanding Litter-Robot Lights

Your Litter-Robot has three lights: a power indicator light, a waste drawer full indicator light, and a status indicator light. Let's break down what each light means:

The power indicator light is a small, white light on the front of the Litter-Robot. It should be on at all times when the unit is plugged in. If it's off, your Litter-Robot might not be receiving power. The waste drawer full indicator light is a larger, white light on the front of the unit. It flashes when the waste drawer is full and needs to be emptied. Lastly, the status indicator light is a larger, blue light on the front of the unit. It displays various patterns and colors to communicate the Litter-Robot's status.

If the power indicator light is off, your Litter-Robot isn't receiving power. Check if the unit is properly plugged in and the power outlet is working. You can test the outlet by plugging in another device. If the outlet is fine, the issue might be with the power cord. Inspect it for any damage or fraying. If everything seems okay, try resetting your Litter-Robot by unplugging it, waiting for 30 seconds, and then plugging it back in.

If the power indicator light still doesn't turn on, it might be time to contact Litter-Robot's customer support or check your warranty for a replacement.

If the waste drawer full indicator light is flashing, it's time to empty the waste drawer. The Litter-Robot will stop cleaning cycles when the waste drawer is full to prevent overflow. To empty the drawer, simply open it and remove the waste. After emptying, the light should turn off. If it doesn't, try resetting your Litter-Robot.

If the light continues to flash after emptying the drawer, there might be an issue with the waste drawer sensor. In this case, you should contact Litter-Robot's customer support for further assistance.
