How To Fix Roomba Not Charging On Dock? Complete Fix Guide

Your Roomba not charging on dock and you’re wondering how to fix it?

Luckily for you, there are more than enough solutions for you to try and at least one of them will either solve your issue or expose the origin.

To fix a Roomba that isn’t charging when on the dock, clean the contact points and switch the outlet. Next, clean the docking station, reset the Roomba and replace the batteries. Then fixate the battery position, and perform a factory reset.

Let’s first get familiar with the possible causes that might have impacted your Roomba’s functionality to charge when on the dock.

Why Roomba Not Charging On Dock At All?

If when you plug your Roomba the charging light first comes on and then goes off instantly, it might be related to a fault in the connection with the charging poles.

If the dock’s charging poles don’t make good contact with Roomba’s battery transmitters, it is possible that a slight charge will be detected for a little while, which will make the lights go on.

Keeping that in mind, here is what else might have happened to your Roomba:

1. Contact Points Issue

Dust on the contact points of your Roomba and the dock might be the reason why you’re unable to charge your device.

2. Outlet Fault

A conditional fault with the outlet might impact the electricity that is reaching your Roomba.

3. Wrong Battery Position

Incorrectly inserted batteries might be the reason why your Roomba is getting a slight charge but then goes off.

4. Battery Issue

A battery issue might also cause your Roomba not to charge while on the dock.

5. Power Adapter Issue

If your Roomba charging dock’s power adapter has interruptions, you might have to replace it to fix the issue.

Now that we’ve taken a look at what might be causing the issue, let’s learn what are the possible ways to fix it in a matter of minutes.

How To Fix Roomba Not Charging On Dock Light Comes On Then Goes Off?

Before we proceed, try restarting Roomba from the CLEAN button. Once restarted, try to charge it again from the dock and if it doesn’t work, proceed with the solutions down below.

Solution #1 Power Cycle The Dock

The first and most easy task you can do is power cycle your dock. This will actively discharge the device from any remaining electricity and might save you some troubleshooting.

Here is how to power cycle your Roomba charging dock:

1. Unplug the dock’s power adapter from the power source.
2. Unplug the other end of the power adapter and let it lay for 5 minutes.
3. Once the dock has discharged (feels cold to the touch), position the power adapter and test.

Once the power cycle is complete, try recharging the Roomba from the charging dock. If it does not work, proceed with the next solution.

Solution #2 Clean The Charging Dock

The most widely recommended solution for users who cannot charge their Roomba on the dock is to clean the dock.

If the contact points are all covered in dust or other substances that might be preventing the electricity from going through and your Roomba won’t charge until further notice.

To clean your charging dock, follow these steps:

1. Unplug the charging dock from the power source.
2. Grab a wet napkin as well as a dry napkin.
3. With the wet napkin, clean the two charging poles where your Roomba goes in and dry them up with the other napkin.
4. Next, use a vacuum cleaner to clean the dock’s hardware.
5. Clean the Roomba’s charging entries.

Once done, try recharging your Roomba from the dock. If it’s still not working, proceed with the next solution.

Solution #3 Fixate Battery Position

It is possible that your Roomba’s batteries moved and are not receiving a good charge from the charging dock.

For this solution, you will have to take a look at your Roomba’s batteries and fix their position.

Here is how to fix Roomba’s battery position:

1. Turn your Roomba upside down and turn it OFF.
2. Open the 5 screws on the base of the Roomba.
3. Remove the battery cover and push the batteries down until you’re certain they are in touch with the contact poles.
4. Close the battery compartment and screw it tightly.

If that solution didn’t help, then perhaps you might have to consider replacing your Roomba’s batteries in order to fix the issue.

Before that, we recommend applying the rest of the solutions.

Solution #4 Use Another Outlet

If the issue is still there after the solutions so far, it is possible that the outlet you’ve plugged your charging dock into isn’t receiving good power.

In case you’re using a charging strip or divider to supply your charging dock with power, make sure to use a wall outlet until the very end of this guide.

Simply unplug your charging dock from the outlet it is currently plugged into and use another proven wall outlet. Check if the robot will now charge through the dock.

Solution #5 Factory Reset Roomba

If nothing worked so far, then we suggest factory resetting your Roomba. This will actively reset the device, hence, you will have to configure the cleaning schedules again.

The reset will eliminate any possible OS glitches that might be preventing the dock charging so you’ll have a pretty good chance against the issue.

Here is how to perform a factory reset on your Roomba cleaning robot:

1. Locate the CLEAN button on Roomba’s hardware.
2. Press the clean button and hold it down for 10 seconds.
3. Once Roomba’s LED starts to flash, let go of the button and wait.

Your Roomba will approximately take about a minute to finish the factory reset and afterward, you will be able to re-configure its settings.

Solution #6 Try With Normal Charging

If Roomba not charging on dock, after all these solutions, you probably know that Roomba can be charged individually without a dock.

Test out Roomba’s ability to charge individually and determine if the issue is with the dock.

To charge Roomba without a dock you will have to grab a power adapter and use the charging port on its hardware with an individual power source.

If Roomba is able to charge on its own with a power adapter, then you will have to replace your charging dock with a new one to resolve the case.
