How do you fix a Roomba that won’t charge?

When your Roomba is not charging, it can disrupt your cleaning routine and leave your floors untouched. However, there are several troubleshooting steps you can take to fix this issue and get your Roomba charging again. Here’s a detailed guide on how to fix a Roomba that is not charging:

Check the power source

Make sure the charging dock is properly plugged into a functional power outlet. Ensure that the power adapter is securely connected to the charging dock and there are no loose connections.

Clean the charging contacts

Over time, dirt and debris can accumulate on the charging contacts of both the Roomba and the charging dock. Use a clean, dry cloth or cotton swab to gently wipe the charging contacts on both the Roomba and the port. This will ensure a proper connection and improve charging efficiency.

Reset the Roomba

Try resetting your Roomba by pressing and holding the CLEAN button for about 10 seconds until you hear a beep. Release the button, and then press it again to turn on the Roomba. This can help resolve any temporary software issues that may be affecting the charging process.

Replace or clean the battery

If your Roomba has an easily removable battery, try removing it and then reinserting it firmly. This can help establish a better connection and fix charging issues. If the battery is dirty or corroded, clean the battery contacts using a clean cloth or a cotton swab dipped in rubbing alcohol. If the battery is old or no longer holding a charge, consider replacing it with a new one.

Check for obstructions

Ensure that there are no objects obstructing the charging dock or the Roomba’s charging contacts. Sometimes, debris or dust can accumulate and interfere with the charging process. Clean the area around the charging dock and make sure there is ample space for the Roomba to dock properly.

Restart the charging process

Sometimes, the Roomba may not immediately start charging when placed on the dock. Try manually placing the Roomba on the charging dock, ensuring it is properly aligned with the charging contacts. If it still doesn’t start charging, press the CLEAN button once to initiate the charging process.

Contact customer support

If none of the above steps resolve the charging issue, it’s recommended to reach out to Roomba’s customer support for further assistance. They can provide specialized troubleshooting guidance or arrange a repair or replacement if necessary.

By following these steps, you can effectively troubleshoot and resolve the issue of your Roomba not charging. Regular maintenance, cleaning, and proper care will help ensure that your Roomba stays charged and ready to keep your floors clean.

Tips for Preventing Roomba Charging Issues in the Future

To ensure a hassle-free cleaning experience with your Roomba, here are some unique and SEO-friendly tips to prevent charging issues in the future:

Ensure Proper Placement of the Home Base: The Roomba’s home base serves as its charging station. Make sure it is placed on a flat, stable surface and positioned in a location with good accessibility. Avoid placing it in cramped or obstructed areas that may interfere with the Roomba’s docking process.

Avoid Excessive Heat or Cold: Extreme temperatures can affect the Roomba’s battery life and charging capabilities. Keep your Roomba and its home base away from direct sunlight, heaters, or areas with extreme cold to prevent any adverse impact on charging performance.

Keep Firmware Updated: Regularly check for firmware updates from the Roomba manufacturer and install them as recommended. Firmware updates often include bug fixes and enhancements that can improve Roomba’s charging efficiency.

Maintain Battery Health: Follow the manufacturer’s guidelines for maintaining the Roomba’s battery health. Avoid frequent deep discharges and ensure the Roomba is charged regularly to optimize battery performance.

By implementing these tips, you can help prevent charging issues with your Roomba and ensure a consistently efficient and effective cleaning experience.

How To Know Your Roomba Needs A New Battery?

Signs That Your Roomba Needs a New Battery:

  • Shortened Cleaning Time: If your Roomba used to clean your entire space on a single charge but now runs out of battery quickly and leaves areas untouched, it could be a sign of a failing battery.
  • Reduced Suction Power: A weak or diminished suction power during cleaning sessions may indicate a deteriorating battery. The Roomba relies on a robust battery to generate the necessary power for effective suction and debris pickup.
  • Difficulty Docking: If your Roomba struggles to find its way back to the charging dock or repeatedly fails to dock properly, it could be a symptom of a battery not holding enough charge for a complete cleaning cycle.
  • Inconsistent Cleaning Patterns: A battery nearing the end of its lifespan may cause erratic cleaning patterns, such as random movements or incomplete coverage, as the Roomba’s power fluctuates during operation.
  • Extended Charging Time: If your Roomba takes significantly longer to charge than it did previously, it may indicate that the battery is no longer holding a full charge capacity.
  • Battery Error Messages: Pay attention to any battery-related error messages or indicators on your Roomba’s display. These warnings can provide valuable insights into the health of the battery.
  • Age and Usage: Consider the age and usage of your Roomba. Generally, Roomba batteries last for a certain number of charging cycles (typically around 300-500 cycles) before experiencing a noticeable decline in performance.

If you notice one or more of these signs, it’s likely time to replace the battery of your Roomba.


In conclusion, there can be various reasons why your Roomba is not charging. It could be due to a loose connection, dirty charging contacts, a faulty battery, or other issues. By following the troubleshooting steps mentioned above, you can often resolve the charging problem and get your Roomba back to its cleaning duties.

Remember to check the power source, clean the charging contacts, reset the Roomba, inspect for obstructions, and restart the charging process. If the issue persists, it’s advisable to contact Roomba’s customer support for further assistance. Regular maintenance and care will help ensure optimal performance and keep your Roomba running smoothly.
