Identifying Common Roomba 690 Charging Culprits
When your Roomba 690 fails to charge, the cause typically falls into one of a few key categories. Before diving into complex fixes, it’s essential to pinpoint the likely source of the problem.
Power Source and Supply Problems
The issue may not be with your Roomba at all, but rather with the power source it relies on.
- Faulty Outlet: The first and simplest check is to ensure the wall outlet is working. Plug another device, like a lamp or a phone charger, into the same outlet to confirm it delivers power.
- Insecure Connections: Verify that the charging station’s power cord is plugged securely into the wall outlet and into the Home Base itself. The power indicator light on the station should be illuminated.
- Damaged Charger: Inspect the power cord and charging station for any signs of physical damage, such as frays, cuts, or bent prongs. If the power light on the base does not turn on even when plugged into a confirmed working outlet, the charger itself may have failed and will need to be replaced. If your Roomba’s charging station or power cord is damaged, a replacement is necessary to ensure proper power delivery to the robot.

Dirty or Poor Connections
For electricity to flow from the base to the robot, a clean and solid physical connection is paramount. Over time, dust and grime can interrupt this connection.
- Contaminated Contacts: The two metal charging contacts on the Roomba’s underside and the corresponding contacts on the Home Base are prone to collecting dust and debris. This buildup creates a barrier that prevents proper charging.
- Improper Alignment: The Roomba needs to be seated snugly against the Home Base for the contacts to meet correctly. If it’s slightly askew or not pushed all the way back, it won’t be able to charge.
- Physical Obstructions: Check the area around the Home Base. A throw rug, a piece of furniture, or even a stray toy can prevent the Roomba from docking properly and making a solid connection.
Battery-Related Faults
The rechargeable battery is the heart of your Roomba, and like all batteries, it has a finite lifespan and can experience issues.
- Degraded Battery Health: After hundreds of charge cycles, the Roomba’s lithium-ion battery will naturally degrade and lose its ability to hold a charge effectively. If your Roomba is several years old and its runtime has significantly decreased, the battery may be at the end of its life.
- Temporary Glitch: Sometimes, the battery’s internal management system can get stuck in a faulty state. A simple reset can often resolve this without needing a full replacement. If your Roomba’s battery is no longer holding a charge, replacing it can restore your robot’s runtime and charging capabilities.

Software and Firmware Glitches
The “smart” part of your smart vacuum is run by software, and like any software, it can encounter bugs or glitches that affect core functions, including charging.
- Outdated Firmware: iRobot periodically releases firmware updates to fix bugs and improve performance. If your Roomba is running on outdated firmware, it could be the source of the charging error.
- Corrupted State: A software crash or data corruption can sometimes put the Roomba into a state where it no longer recognizes the charging base correctly. A factory reset can often clear these deep-seated software issues.
Potential Mechanical Failures
In some cases, the problem is due to physical damage to the components themselves.
- Damaged Charging Port: Inspect the charging port on the Roomba for any signs of damage. A bent or broken internal pin can prevent the charging cable from making a connection.
- Misaligned Contacts: The metal contacts on the robot or base can become bent or pushed in, preventing them from touching. They should be flat and properly seated. If you suspect a hardware failure that isn’t easily fixable, professional service may be required.
A Step-by-Step Guide to Troubleshooting
Follow these steps in order, moving from the simplest solutions to the more complex ones. This methodical approach will help you isolate and fix the issue efficiently.
Step 1: Verify the Power Supply
Begin with the basics. Confirm that the wall outlet is providing power by testing it with another appliance. Once confirmed, ensure the Home Base charger is firmly plugged into the outlet and that its power indicator light is on. A lack of light on the base points directly to a problem with the charger or the outlet.
Step 2: Clean the Charging Contacts
This is one of the most common and effective fixes. Unplug the Home Base from the wall. Take a soft, dry cloth (a microfiber cloth works perfectly) and wipe down the metal charging contacts on the Home Base. Next, turn the Roomba over and thoroughly clean the corresponding contacts on its underside. Remove any visible dust, hair, or grime that could be interfering with the connection.
Step 3: Ensure Proper Alignment
Place the Roomba back on its Home Base manually. Make sure it sits squarely and snugly against the dock. You should see the Roomba’s light ring illuminate or hear a tone indicating that charging has begun. If it docks but doesn’t charge, try repositioning it slightly to ensure the contacts are perfectly aligned. Also, clear any rugs or objects from around the base that might be preventing a solid dock.
Step 4: Check for Software Updates
If the physical connection seems fine, the issue could be software-related. Connect your Roomba 690 to your home Wi-Fi network and open the iRobot HOME App on your smartphone. The app will notify you if a firmware update is available. Proceed with the installation, as updates often contain crucial bug fixes related to charging and battery management.
Step 5: Perform a Battery Reset
A battery reset can resolve temporary glitches without erasing your settings. To do this, first remove the Roomba from its Home Base. Then, press and hold the “CLEAN” button for about 10-15 seconds, until the light ring swirls. Release the button and allow the robot to fully reboot. Once it has rebooted, place it back on the charging station to see if the issue is resolved.
Step 6: Consider a Factory Reset
A factory reset is a more drastic step, as it will erase all your custom settings, schedules, and Wi-Fi connections, returning the Roomba to its original out-of-the-box state. This should only be performed if other steps have failed. To initiate a factory reset, press and hold all three buttons (“Dock,” “Spot Clean,” and “CLEAN”) simultaneously for about 10-15 seconds until the robot makes a tone. After the reset, you will need to set it up again through the iRobot app.
Step 7: When to Contact Support
If you have completed all the steps above and your Roomba 690 still refuses to charge, it may be time to seek professional help. The issue could be a failed battery that needs replacement or an internal mechanical failure. Contact iRobot customer support with the details of your troubleshooting efforts. They can provide further guidance, diagnose the problem, and discuss repair or replacement options.
Decoding Roomba 690 Error Codes
Your Roomba can often tell you what’s wrong through error codes. If your robot speaks an error message or flashes a code, you can use the iRobot HOME App to get more details. Here are some charging-related codes:
Error Code 10
This code signals a problem with the charging system. It often means the robot is not able to communicate with the Home Base. The most common solutions are to clean the charging contacts thoroughly and ensure the Roomba is properly aligned on its dock.
Error Code 11
Error 11 typically points to a low battery condition that has become critical. This can happen if the Roomba gets stuck somewhere and its battery drains completely. Ensure it is placed correctly on a fully powered base and allow it to charge uninterrupted for several hours. If the error persists, performing a battery reset may be necessary.
Error Code 12
This code indicates a more general charging fault. It can be triggered by a variety of issues, from a deeply discharged battery to a faulty charging station. If cleaning the contacts and resetting the battery do not clear this error, you may need to consider replacing the battery or the Home Base. If your Roomba’s battery or charging station is faulty and causing Error 12, replacing the affected component may resolve the issue.
