When your reliable Roomba 960 suddenly goes dark, with no lights showing on either the robot or its home base, it can be a frustrating experience. This lack of power signals an interruption somewhere in the charging process, but it doesn’t automatically mean a catastrophic failure. Often, the root cause is a simple, fixable issue that you can resolve at home without needing a service call or replacement.
This comprehensive guide will walk you through every step of diagnosing and fixing the “no lights” issue on your Roomba 960. We will explore everything from basic power checks to more advanced reset procedures. You will learn how to identify common causes, apply effective solutions, and implement a proactive maintenance routine to prevent this problem from happening again, ensuring your robotic vacuum is always ready to clean.
Diagnosing the “No Lights” Problem
Before diving into complex solutions, a systematic check of the basics can often pinpoint the problem quickly. When faced with an unresponsive Roomba and a dark home base, start with the most obvious potential culprits and work your way inward.
First, verify the power source itself. Ensure the power cord is firmly plugged into both the wall outlet and the back of the home base. It’s easy for these connections to become loose. To rule out a faulty outlet, unplug the Roomba’s cord and test the outlet with another small appliance, like a lamp or a phone charger. If the other device works, you know the outlet is supplying power.
Next, give the home base a close inspection. Examine the two metal charging contacts on the base for any visible dirt, dust, or corrosion. These contacts are crucial for transferring power to the robot. Also, look for a small green LED indicator light on the back of the home base; if this light is on, the base is receiving power, and the issue likely lies with the robot or the connection between the two.
Finally, turn your attention to the robot. A completely drained battery can prevent any lights from appearing. Check the corresponding charging contacts on the underside of the Roomba for any debris or wear. A clean, unobstructed connection between the robot and the base is essential for a successful charge.
Step-by-Step Solutions for Common Causes
If the initial diagnosis doesn’t reveal a simple fix, it’s time to investigate the most common causes for a Roomba 960 that won’t power on or charge. Each of these issues has a straightforward solution you can perform.
Addressing Power Supply Issues
A faulty power cord is a frequent offender. Inspect the entire length of the cord for any visible damage, frays, or kinks. If you notice any damage, the cord should be replaced immediately. If the cord appears fine but the outlet test confirmed the outlet is dead, simply move the home base to a different, functioning electrical outlet.
If your Roomba’s power cord is damaged or not functioning, replacing it can restore power to your home base and robot.

Resolving Battery Problems
The lifeblood of your Roomba is its battery. If the battery is completely depleted, the robot will show no signs of life. Place the Roomba manually onto the home base, ensuring the metal contacts on the robot align perfectly with the contacts on the base. You may need to press down gently to secure the connection. Leave it to charge for several hours. If it still shows no lights, the battery may be old, damaged, or at the end of its lifespan and could require a replacement.
If your Roomba’s battery is no longer holding a charge or appears to be dead, a new battery can bring your robot back to life.

Fixing Dirty or Corroded Charging Contacts
This is one of the most common yet overlooked causes of charging failure. Over time, dust, pet hair, and grime can build up on the charging contacts, creating a barrier that prevents electricity from flowing.
Simple Cleaning
For routine maintenance, use a soft, dry cloth to wipe the metal contacts on both the robot and the home base. If the grime is a bit more stubborn, you can use a lightly dampened cloth.
Deep Cleaning
For significant buildup or minor corrosion, a Mr. Clean Magic Eraser is highly effective. Lightly dampen the eraser and gently scrub the contacts. For tougher corrosion, you can use very fine-grit sandpaper. Gently sand each contact about 10 times to remove the oxidized layer, then wipe away any residue with a dry cloth. This deep cleaning should be done carefully and only when necessary, but it can often resurrect a seemingly dead charging connection. This process should be repeated every few weeks for preventative maintenance.
What to Do About a Malfunctioning Home Base
If the small green LED on the back of the home base is not lit even when plugged into a working outlet, the base itself may have an internal fault. The first step is to perform a home base reset, which is detailed in the next section. If a reset doesn’t work, and you’ve confirmed the power cord is functional, the home base may need to be replaced.
If your Roomba’s home base is no longer powering on or charging your robot, replacing it is necessary to resume normal operation.

Clearing Firmware and Software Glitches
Sometimes, the problem isn’t physical but digital. A software glitch can cause the Roomba to become unresponsive. A stable Wi-Fi connection is necessary for the robot to receive updates and function correctly with the iRobot app. Ensure your home Wi-Fi is working. If you suspect a software issue, performing a reset is the next logical step.
Advanced Reset and Inspection Procedures
When basic troubleshooting doesn’t work, a reset can often clear internal errors and restore normal function. There are different levels of resets for your Roomba, from a simple reboot to a full factory reset.
Performing a Soft Reset on the Robot
A soft reset is like rebooting your computer; it clears temporary glitches without erasing your settings. To do this, press and hold the large “Clean” button on the top of your Roomba 960 for approximately 10 seconds. You will know it’s working when the lights flash. Release the button and allow the robot to restart.
Executing a Hard Reset on the Robot
A hard reset, or factory reset, restores the Roomba to its original default settings. This should be used as a last resort, as it will erase custom schedules and settings. To perform a hard reset on the Roomba 960, press and hold the “Spot” button and the “Clean” button simultaneously for about 10 seconds. Release the buttons and wait for the robot to reboot completely. It will emit a sound and may flash its lights as it resets.
How to Reset the Home Base
The home base can also be reset to clear any potential electrical faults. This is a simple process:
- Disconnect the power cord from the back of the home base.
- Wait for at least 30 seconds.
- Reconnect the power cord firmly.
- Wait for the base to power on. The green indicator light on the back should illuminate.
When to Consider Professional Help
If you have meticulously followed all the troubleshooting and reset steps and your Roomba 960 still shows no signs of life, the problem may be more severe. A faulty internal circuit board is a possibility that requires professional intervention. At this point, it is best to contact iRobot customer support for further assistance and to discuss potential repair or replacement options.
Proactive Maintenance for Your Roomba 960
The best way to deal with problems is to prevent them from happening in the first place. A consistent maintenance routine will keep your Roomba 960 in peak condition and minimize the chances of charging failures.
The Importance of Regular Cleaning
Regular cleaning is paramount. After each cleaning cycle, empty the dustbin and clean the filter. Most importantly, make it a habit to wipe down the charging contacts on both the robot and the home base every couple of weeks with a dry cloth to prevent residue buildup.
Best Practices for Battery Care
To maintain battery health, always store your Roomba on its home base when it’s not in use. This ensures the battery remains topped off and ready for the next cleaning job. The Roomba system is designed to prevent overcharging, so leaving it on the base is the recommended practice.
Keeping Software and Firmware Current
Ensure the iRobot app on your smartphone is always updated to the latest version. The app is the gateway for firmware updates that iRobot pushes out to fix bugs, improve performance, and add new features. Regularly check the app for any notifications or alerts related to your robot’s performance.
Frequently Asked Questions (FAQ)
Why did the light on my Roomba’s home base turn off while it’s charging?
This is a normal, energy-saving feature. After the Roomba is fully charged and for a period while it is charging, the indicator lights on the home base and the robot may turn off to conserve power. The Roomba is still connected and maintaining its charge even when the lights are off.
How do I properly clean the charging contacts on my Roomba?
For regular cleaning, a soft, dry cloth is sufficient. For more significant dirt or buildup, you can use a lightly dampened Mr. Clean Magic Eraser. Rub the metal contacts on both the robot and the base gently, then wipe them dry. This should be done every two weeks to ensure a reliable connection.
What is the difference between a soft reset and a hard reset?
A soft reset (holding the “Clean” button) is a simple reboot that clears temporary errors without deleting your saved data, like cleaning schedules or Wi-Fi settings. A hard reset (holding “Spot” and “Clean” buttons) is a factory reset that an erase all your custom data and restores the robot to its original, out-of-the-box settings.
Will my Roomba lose its settings if I reboot it from the iRobot app?
No. Rebooting the Roomba from the Product Settings menu in the iRobot app is equivalent to a soft reset. The robot will save its data, reboot itself, and then reconnect to your Wi-Fi network and return to normal operation with all its settings intact.
Conclusion
Encountering a Roomba 960 with no lights on either the robot or its home base can be alarming, but it is rarely a sign of a terminal problem. By following a logical troubleshooting path—starting with the power source, inspecting for physical obstructions on the charging contacts, and performing resets when necessary—you can often resolve the issue yourself. The key to a long and effective life for your robotic vacuum lies in consistent, proactive maintenance. Regularly cleaning the contacts, emptying the bin, and keeping the software updated will prevent most common problems and ensure your Roomba 960 is always charged up and ready to keep your floors clean.
