Why Isn’t My Roomba Charging?
The most common reasons a Roomba won’t charge are dirty charging contacts, a faulty charging dock, or a worn-out battery. Let’s start by checking the charging contacts on both the Roomba and the dock.
How to Clean Roomba Charging Contacts
- Power off the Roomba and remove it from the charging dock.
- Flip the Roomba over and locate the metal charging contacts on the bottom of the robot.
- Use a soft, dry cloth to gently wipe away any dirt, dust, or debris on the contacts.
- Also clean the metal charging pins on the charging dock using the cloth.
- Reconnect the Roomba to the dock and check if the charging indicator light turns on.
What If the Roomba Still Won’t Charge?
If the Roomba still isn’t charging after cleaning the contacts, the issue may be with the battery itself. Over time, Roomba batteries can wear out and lose their ability to hold a charge. You may need to replace the battery if it’s no longer holding a charge.
How to Replace a Roomba Battery
- Power off the Roomba and remove it from the charging dock.
- Flip the Roomba over and locate the battery compartment cover.
- Use a Phillips #1 screwdriver to remove the screws and open the battery compartment.
- Carefully disconnect the old battery and replace it with a new OEM Roomba battery.
- Reassemble the Roomba and place it back on the charging dock to test the new battery.
Preventing Future Roomba Charging Issues
To help avoid Roomba charging problems in the future, be sure to keep the charging contacts clean by wiping them down regularly with a soft cloth. Additionally, replace the battery every 12-18 months, or when you notice the runtime decreasing significantly.
