Roomba Won’t Charge: 7 Easy Ways To Fix The Problem Now

Keeping your floors clean can be a hassle, but with Roomba, you can sit back and let the little robot do the work. However, what happens when your Roomba won’t charge? Don’t worry; there are ways to fix it quickly.

This article will explore the common causes of Roomba charging problems and provide simple solutions to get your Roomba back up and running in no time.

We’ve covered you whether it’s a dirty charging contact or a faulty battery. So, let’s get started and troubleshoot your Roomba charging issue.

Why Roomba Won’t Charge?

Roomba won’t charge if there are underlying issues with the battery, charging station, charging contacts, or power supply. Here are the various causes that could lead to this issue:

1. Dirty Contacts

Roomba’s charging contacts are located on the bottom of the robot and the Home Base charging station. If these contacts are dirty or obstructed by dust, hair, or debris, they may not connect well and prevent the battery from charging.

To fix this, try cleaning the contacts with a dry cloth or compressed air and wiping the dock and robot’s charging pins with a slightly damp soft cloth. Be careful not to use water or harsh chemicals that may damage the components.

2. Defective Battery

Roomba’s lithium-ion batteries are rechargeable batteries designed to last hundreds of charging cycles, but they can eventually wear out and lose their capacity to hold a charge.

If your Roomba’s battery life has significantly decreased or the robot won’t charge, it may be time to replace it. You can buy an original battery from iRobot or third-party sellers, but be aware of counterfeit or low-quality batteries that may be unsafe or incompatible with your model.

3. Faulty Power Supply

Roomba’s power supply converts AC power from the wall outlet to DC power for the robot and the dock, which can also cause charging problems if malfunctions.

If you suspect that the power supply is the culprit, you can try resetting it by unplugging it from the wall for a minute, then plugging it back in and retrying the charging process. You can also use a multimeter to test the power supply’s output voltage and see if it matches the specifications.

4. Software Glitch

Roomba’s software can occasionally encounter bugs, error codes, or glitches affecting its charging behavior.

Suppose you have recently updated your Roomba’s firmware or experienced any other software-related issues. In that case, reset the robot by holding the CLEAN button for about 20 seconds until you hear a beep. This should force the Roomba to reboot and reload the firmware, which may fix the charging problem.

5. Physical damage

Roomba’s components, including the battery, charging contacts, and power supply, can be susceptible to physical damage from drops, impacts, or exposure to extreme temperatures or moisture.

If your Roomba has been damaged or exposed to harsh conditions, it may not charge properly. In this case, you may need to contact iRobot’s customer support or a professional repair service to assess the damage and recommend a solution.

By addressing these common causes of Roomba charging problems, you can restore your robot’s functionality and enjoy its cleaning benefits again.

However, if none of these solutions work or you have concerns about your Roomba’s performance, feel free to seek further assistance online from iRobot’s resources or other Roomba users.

How to Fix a Roomba that Won’t Charge?

If you’re facing the issue of your Roomba not charging, don’t worry. You can try several fixes to get your Roomba back up and running. Here are some of the most common fixes that you can try:

1. Check the Charging Contacts

One of the most common causes of a Roomba not charging is filthy or blocked charging connections on either the Roomba or the charging dock.

Check to make sure the charging connections are clean and clear of debris. Using a dry cloth, you may carefully clean the charging connections on the Roomba and the charging dock.

2. Reset the Roomba

Another solution is to try doing a factory reset of the Roomba. This can be done by holding the “CLEAN” button on the Roomba for about 10 seconds until you hear a beep. Then, release the button and let the Roomba reset itself.

3. Check the Battery

If the battery is dead, the Roomba won’t charge. So, check the battery status by pressing and holding the “CLEAN” button on the Roomba.

If the battery indicator light is not blinking, then the battery is either fully charged or completely dead. If it’s completely dead, you should replace the battery.

4. Check the Power source

Check that the charging station is hooked to a functioning power outlet. You can plug another appliance into the same outlet to check if it’s working.

5. Check the Power cable

The power cable can also be the cause of your Roomba not charging. Check to see if there is any cable damage or if it is plugged into the charging dock properly.

6. Replace the Charging dock

If none of the above solutions work, you may need to replace the charging dock. Sometimes the port can become damaged or faulty over time.

7. Replace the Battery

If your Roomba is still not charging, you may need to replace the battery even after trying all the above solutions. It’s vital to get the correct replacement battery that matches the specifications of your Roomba model.

By trying out these solutions, you can get your Roomba back to working condition and enjoy the convenience of an autonomous vacuum cleaner.
