Why is Roomba not Charging?

Roomba Is Not Charging

There are a few potential causes for your iRobot Roomba robot vacuum to stop charging. Most of the time, it’s because of issues with the Roomba’s link to its home base. If they are not adequately connected, there will be no power transfer.

Most of the time, it concerns how the Roomba is connected to the base station.

However, it isn’t the only issue at hand. Incorrect positioning of the base station is another possible cause. If it shifts when Roomba is trying to park, for instance, the Robot Cleaner may not be able to find it again.

The most common causes of an iRobot’s roomba is not charging are:

  1. The contacts on my iRobot Roomba are filthy.
  2. There is dirt in the base station’s contacts.
  3. The charging station is unstable.
  4. There is an issue with the insertion of the plug into the socket.
  5. The base station cable is not attached correctly.
  6. One of the power cables has snapped.
  7. The battery has run out of energy.

The battery in Roomba might be dead. It is probably a Roomba, as it has a flashing red light. In such a situation, the Roomba’s battery must be changed.

How to fix the Roomba not charging issue?

Roomba is not Charging

Clean the contacts

Your Roomba will only charge effectively if it makes complete electrical contact with the charging dock. The Roomba and its charging base communicate via a pair of tiny metal plates. 

These should be checked when your Roomba won’t charge since they are susceptible to oxidation and dirt buildup. 

Wipe the contacts and their surrounding area with a moist cloth, then use a clean cloth soaked in rubbing alcohol to polish the contacts until they sparkle and the dirt has been gone.   

Reboot your Roomba

Your charging issue may be caused by a bug in the software rather than the hardware. 

If so, a short reboot might bring your Roomba back up and running. You must try this first before going on to more involved solutions. 

  1. If you’re unsure how to reset your Roomba, see the manual for your specific model. 
  2. Holding down the Home, Clean buttons and Spot Clean at once will reset most Roombas.
  3. To release the Clean button, wait for the surrounding light to turn on. In some models, you will hear the vacuum beep sound while pressing the buttons.

Clean the Wheels

You must clean the wheels in the same manner, both the primary driving wheels and the caster wheel in front. 

Roomba Is Not Charging

While it may not be immediately apparent, debris on the wheels may prevent the Roomba from charging.

If the dirt raises the device’s base, it makes it more difficult for the contacts to make a firm connection and begin the charging process.

Reinstall the battery

The battery may not be correctly positioned in the Roomba, preventing a charge. Make sure the plastic tab, if present, has been removed from your Roomba before using it for the first time. 

But if you’ve owned the Roomba for a time, the battery could not be in the correct location. 

To access the battery, you’ll need to invert the Roomba, unscrew the battery cover, and pull the battery out. Put it back where it belongs and secure the screws.

Install a new battery

The Roomba’s battery may have lost its capacity to retain a charge if it has been cleaned for a long time. It’s designed to withstand repeated cleanings for an extended period.

However, all batteries die at some point. iRobot sells new batteries, and you may also use batteries from other brands if they are compatible.

After that, your Roomba should function as well as it did when you first got it.

Move the charging station

It’s conceivable that the charging station isn’t activated correctly if the Roomba still refuses to take charge. 

To verify, try switching the plug to a different outlet. Alternatively, ensure that the plug is not connected to a wall switch.  

Get in touch with iRobot’s support team

If you’ve exhausted all options and your Roomba still won’t take charge from the dock, there’s likely a significant hardware issue with the dock or a power component within the vacuum that you won’t repair on your own.

How long does a Roomba battery last? 

If you take good care of your robot’s battery, it should live for at least 2-3 years before it dies. 

Here are some ways to take care of your Roomba’s batteries so that it lasts longer and continues to work at a high level: 

1. To ensure proper operation, only iRobot batteries should be used.  

2. If you don’t have access to or don’t want to use ship mode, you should store the battery away from the robot in a cold, dry place.  

3. Verify that the robot is being charged in a cool, shaded area at room temperature. 

4. To get the most out of your battery, you should charge it to complete once a month.

5. Leave your robot charging on the Home Base or Clean BaseTM when not in use.  

6. Wash your robot often. It will have to work harder and drain the battery sooner if it becomes blocked with hair or other particles. 

7. After each usage, immediately plug your robot back in to charge.  

iRobot advises putting your Roomba into ship mode if it won’t be used for over a few weeks. Then, put it away somewhere dry and cold.

What is the best way to clean a Roomba battery?

A Roomba, or any other robot vacuum, may be difficult to clean.

For your Roomba to function at peak performance, its various filters and other components must be routinely cleaned.

Lucky for you, we’ve compiled a thorough explanation that will show you how to:

How do I know if my Roomba needs a new battery?

The iRobot HOME App provides a straightforward approach to determining the battery’s current condition.

The current charge level of the battery will be represented by a battery icon, which will be located in the upper-right-hand corner of the screen.


When problems arise, like the iRobot Roomba is not charging, you have a few options. Before anything else, check the charging connections on the cleaner’s wheel or the caster base to see whether they are covered in any dust or grime. 

This buildup hinders contact between the vital components, resulting in problems such as the iRobot not charging.

Making sure you obtain the proper battery model is also vital for giving your robot enough juice to function. 

Contact the iRobot support staff at any time if you continue to experience the Roomba won’t charge error.
