Common Roomba 618 Error Messages and What They Mean

Understanding the error messages your Roomba 618 displays is the first step to troubleshooting. These messages are your Roomba’s way of telling you what’s wrong, allowing you to quickly identify the problem. Here’s a breakdown of some common error messages:
- “Error 1” or “Error 2”: Usually indicates a problem with the cleaning head module. The brushes might be tangled with hair or debris, preventing them from spinning freely.
- “Error 5”: This error typically means that the Roomba is experiencing a wheel problem. One or both wheels might be stuck or unable to rotate.
- “Error 6”: This error message suggests that the Roomba’s cliff sensors are dirty or malfunctioning, causing it to think it’s near a drop-off even when it isn’t.
- “Charging Error”: This indicates an issue with the charging process. It could be a problem with the charging station, the battery, or the Roomba’s charging contacts.
Diagnosing Battery Issues in Your Roomba 618
Battery problems are a frequent cause of Roomba malfunctions. If your Roomba 618 isn’t charging, isn’t holding a charge, or is dying quickly, here’s how to diagnose and address the issue:
- Check the Charging Contacts: Ensure that the charging contacts on both the Roomba and the charging station are clean and free of debris. Use a clean, dry cloth to wipe them.
- Verify the Power Supply: Make sure the charging station is properly plugged into a working outlet. Test the outlet with another device to confirm it’s providing power.
- Reseat the Battery: Remove the battery from the Roomba and reinsert it, ensuring it’s properly connected.
- Monitor Charging Time: Allow the Roomba to charge for at least 16 hours to see if it recovers. A new battery may require a full charge cycle to reach its optimal performance.
- Consider Battery Replacement: If the battery still isn’t holding a charge after these steps, it may be time to replace it. Roomba batteries have a limited lifespan and will eventually need to be replaced.
Resolving Brush and Cleaning Head Problems
A common issue with the Roomba 618 is tangled brushes or a malfunctioning cleaning head. Here’s how to troubleshoot and resolve these problems:
- Turn off the Roomba: Always turn off the Roomba before performing any maintenance or troubleshooting.
- Remove the Brushes: Take out the brushes from the cleaning head module.
- Clean the Brushes: Remove any hair, string, or debris that may be tangled around the brushes. Use the cleaning tool provided with your Roomba or a pair of scissors to carefully cut away the debris. If you need replacement brushes or a cleaning tool, consider this Roomba accessory kit.
- Inspect the Brush Bearings: Check the brush bearings for any buildup of dirt or debris. Clean them thoroughly to ensure the brushes can spin freely.
- Reinstall the Brushes: Place the cleaned brushes back into the cleaning head module, ensuring they are properly seated.
- Test the Roomba: Turn the Roomba back on and run a cleaning cycle to see if the problem is resolved.
Pro Tip:
Regularly cleaning the brushes (at least once a week) can prevent buildup and ensure optimal performance.
Addressing Navigation and Movement Problems

If your Roomba 618 is bumping into walls, getting stuck, or not covering the entire floor, it may be experiencing navigation problems. Here’s how to troubleshoot and resolve these issues:
- Check the Cliff Sensors: The cliff sensors are located on the bottom of the Roomba and prevent it from falling down stairs. Clean these sensors with a dry cloth to remove any dust or debris that may be interfering with their function.
- Clear Obstacles: Remove any small objects, such as cables, socks, or toys, that may be obstructing the Roomba’s path.
- Ensure Adequate Lighting: Roomba relies on visual cues for navigation, so ensure the room is adequately lit.
- Reset the Roomba: A reset can sometimes resolve navigation problems. Press and hold the “Clean” button for about 15 seconds until the Roomba restarts.
- Check the Wheels: Inspect the wheels for any obstructions or damage. Make sure they can rotate freely.
Troubleshooting Charging Station Issues
If your Roomba 618 isn’t charging properly, the problem might be with the charging station. Here’s how to troubleshoot charging station issues:
- Verify the Connection: Ensure the charging station is properly plugged into a working outlet.
- Check the Charging Contacts: Make sure the charging contacts on the base station are clean and free of debris.
- Reposition the Base Station: Place the charging station on a hard, level surface against a wall. Ensure there are no obstructions around the base station.
- Test with Another Outlet: Try plugging the charging station into a different outlet to rule out any electrical issues.
