Litter Robot Cycling Light Flashing: Possible Causes

If you are observing a cycling light flashing on your Litter Robot, there are several possible causes. In this guide, we will cover the most common causes of cycling light flashing and provide step-by-step instructions on how to troubleshoot and resolve the issue.

Full Waste Drawer: If the waste drawer is full or not installed properly, the cycling light may flash. This is a safety feature designed to prevent the device from overloading and causing damage.

Obstructed Sensor: The Litter Robot is equipped with several sensors that are used to detect the presence of a cat and to ensure that the device is functioning properly. If one of these sensors is obstructed or not functioning correctly, the cycling light may flash.


Dirty Sensors: Over time, the sensors on the Litter Robot may become dirty or covered with dust, which can cause them to malfunction and result in the cycling light flashing.

Power Issues: If the Litter Robot is not receiving enough power or if there is an issue with the power supply, the cycling light may flash.

Litter Robot Cycling Light Flashing: How to Fix

Step 1: Check the Waste Drawer

You would want to start by checking the waste drawer. Make sure that it is properly installed and not overfilled. If the waste drawer is full, remove it and empty it into a trash bag.

Once the waste drawer has been emptied, reinsert it into the Litter Robot and check to see if the cycling light has stopped flashing.

Step 2: Check for Obstructed Sensors

If the waste drawer is not the issue, the next step is to check for any obstructed sensors. Carefully examine the interior of the device and make sure that all sensors are clear of debris and functioning correctly. If you find an obstructed sensor, use a clean, dry cloth to gently remove any debris or dust.

Step 3: Clean the Sensors

If the sensors are not obstructed, it may be necessary to clean them. As you continue to operate the Litter Robot, dust and debris can accumulate on the sensors, causing them to malfunction.

To clean the sensors, use a clean, dry cloth to gently wipe away any dust or debris. Avoid using water or cleaning solutions, as this can damage the sensors.

Step 4: Check the Power Supply

If the waste drawer and sensors are not the issue, there may be a problem with the power supply. Make sure that the power cord is properly connected and that the outlet is functioning correctly. You may also want to try plugging the Litter Robot into a different outlet to see if this resolves the issue.

Step 5: Contact Customer Support

If none of the steps above worked for you and you are still experiencing cycling light flashing, it may be necessary to reach out to Litter Robot customer support. They can provide additional troubleshooting steps or arrange for a repair or replacement.

Maintenance Tips for the Litter Robot

The maintenance tips below will ensure that you get the best performance out of the Litter Robot and enhance its lifespan. 

1. Regular Cleaning

One of the most important aspects of maintaining a Litter Robot is keeping it clean. The waste drawer and globe should be cleaned regularly to prevent the buildup of waste, litter, and bacteria. The frequency of cleaning will depend on the number of cats using the device and how often it is used. As a general rule, it is recommended to clean the waste drawer and globe at least once a week. 

To clean the waste drawer and globe, simply remove them from the device, dispose of any waste, and wipe them down with a damp cloth or paper towel. You can also use a mild detergent or cleaning solution to help remove any stubborn stains or odors.

2. Replace Carbon Filter

The carbon filter helps to eliminate odors. It is recommended to replace the carbon filter every 3-6 months, depending on usage. To replace the carbon filter, simply remove the waste drawer and globe, locate the filter, and replace it with a new one.

3. Check for Clogs

You should regularly check for clogs in the Litter Robot to ensure it is functioning properly. If waste or litter becomes clogged in the device, it can cause the cycling light to flash and prevent the device from functioning correctly. 

To check for clogs, remove the waste drawer and globe and inspect the interior of the device for any debris or clogs. Use a cleaning tool, such as a scoop or brush, to remove any clogs or debris.

4. Lubricate Moving Parts

The moving parts of the Litter Robot, such as the motor and gears, should be lubricated periodically to ensure they are functioning correctly. It is recommended to use a silicone-based lubricant for this purpose. Simply apply a small amount of lubricant to the moving parts and run the device for a few cycles to distribute the lubricant evenly.

5. Inspect Power Cord

Regularly inspect the power cord for any signs of damage, such as frayed wires or cuts. If you notice any damage to the power cord, it should be replaced immediately to prevent electrical hazards.

6. Check for Loose Bolts

The Litter Robot is designed to be sturdy and durable, but it is still important to periodically check for any loose bolts or screws. Use a wrench or screwdriver to tighten any loose bolts or screws to ensure the device remains stable and safe.
