Roomba Charging Errors 1, 3, 4, 11, and 19: Solved!
The Roomba, developed by iRobot, is a series of autonomous robotic vacuum cleaners that have greatly simplified the task of keeping homes clean. These devices automatically return to their charging base once the cleaning task is complete or when their battery levels are low.
They charge themselves and stand ready for the next cleaning cycle. However, like all technology, they are not immune to occasional errors. Roomba charging errors, for instance, may prevent the device from working effectively.

Roomba Charging Error 1 and How To Solve It
Charging error 1 signifies that the battery is not connected. This error might occur if the battery has been incorrectly installed or if the battery contacts are dirty or corroded.
To fix this error, ensure that the battery is correctly installed, making sure that it is fully seated and the battery door is securely closed.
If the error persists, clean the battery contacts using a clean, dry cloth or a melamine foam such as Magic Eraser. If the error still continues, the battery might need to be replaced.
Roomba Charging Error 3 and How To Solve It
Charging error 3 indicates that Roomba's charging system isn't working correctly.
The first thing to try in this case is a reset. To reset your Roomba, remove it from the charger, hold down the 'clean' button for about 10 seconds until the device turns off, then place it back on the charging base.
If the error persists, check the charging contacts on both the robot and the home base for debris or damage. Cleaning these contacts can often resolve the issue.
If these steps don't work, contact iRobot customer service for further assistance.
Roomba Charging Error 4 and How To Solve It
Charging error 4 means that the Roomba is failing to charge. This can be due to a faulty charging source or base or an issue with the robot itself.
Firstly, ensure that the charging base is properly connected to a working outlet.
If this does not resolve the issue, try charging the Roomba directly with the AC adapter, bypassing the charging base - plug the charger directly into the Roomba charging port which can be found on its side (model dependent).
If the Roomba charges successfully in this way, the charging base may need to be replaced. If the robot still does not charge, a reset or a battery replacement may be necessary.
Roomba Charging Error 11 and How To Solve It
Charging error 11 is another error indicating a battery issue. This error signifies that the battery is not detected.
This could be due to a misaligned battery or a faulty battery.
Double-check that the battery is properly seated within the device and the battery door is secured. If this does not solve the problem, the battery may need to be replaced.
Roomba Charging Error 19 and How To Solve It
Charging error 19 means that the battery is not correctly installed or recognized.
Similar to error 11, make sure the battery is correctly installed, and the battery door is properly closed.
Also, clean the battery contacts if needed.
If this error continues, the battery might be faulty and may require replacement.
Few Final Words
Troubleshooting Roomba charging errors often involves examining the battery and charging contacts, reseating the battery, performing a system reset, or potentially replacing the battery or charging base.
In some cases, contacting iRobot's customer service may be the best course of action, especially if your device is still under warranty.
Remember that regular maintenance, such as cleaning the charging contacts and ensuring the battery is correctly installed, can help prevent these errors from occurring in the first place.
These tips should help keep your Roomba charged and ready to keep your floors clean. While dealing with technical issues can be frustrating, remember that many of these errors can be solved with a few simple steps. If none of the aforementioned solutions work, the problem may be more serious and might require professional assistance.
Whenever you are unsure about your actions, always check the Owner's Guide and follow official maintenance procedures.
With technology constantly evolving, it's crucial to keep up-to-date with the latest information about your Roomba and its functionality. You can visit the iRobot website or forums for the most recent updates and tips.
Having a Roomba can save you a significant amount of time, freeing you to focus on other tasks while your floors are kept clean.
