🤖 Your Roomba is a hardworking little helper, but like any device, it can run into issues — and not charging is one of the most frustrating. Luckily, most charging problems have simple fixes. Let’s walk through step-by-step solutions to get your Roomba back in action.
🔍 Check the Basics First
Before diving into deeper troubleshooting, make sure the simple things are covered:
- Power source: Ensure the outlet is working by plugging in another device.
- Charging dock connection: Verify the dock is plugged in securely and the light indicators are on.
- Battery placement: If you recently replaced the battery, ensure it’s installed correctly.
🧽 Clean the Charging Contacts
Dust, dirt, and hair can prevent the charging contacts on your Roomba and dock from making a solid connection.
- Turn off and flip the Roomba over.
- Wipe the charging plates with a dry cloth or lightly dampened microfiber.
- Do the same for the dock contacts.
- Avoid using harsh chemicals.
🔋 Check the Battery Health
Batteries lose capacity over time, especially if your Roomba is a few years old.
- If the battery doesn’t hold a charge or drains quickly, it may need replacement.
- Genuine iRobot batteries generally last 2–3 years with regular use.
- Avoid third-party batteries of questionable quality.
🔄 Reset Your Roomba
Sometimes a simple reset can fix charging issues.
- For most models: Press and hold CLEAN for about 20 seconds until you hear a tone, then release.
- Place the Roomba on the dock and check if it begins charging.
⚡ Check the Power Adapter and Dock
If your dock isn’t powering up:
- Inspect the power adapter cable for cuts or damage.
- Try plugging it directly into the Roomba (if supported) to see if it charges without the dock.
- If the dock light doesn’t turn on, it may need replacement.
🌡️ Avoid Extreme Temperatures
Roomba batteries perform poorly if they’re too hot or cold.
- Keep your charging station in a room-temperature environment.
- Avoid placing the dock near heaters, vents, or direct sunlight.
🛠️ When to Call iRobot Support
If none of the above fixes work, it’s time to contact iRobot Customer Care. Persistent charging problems could mean:
- Internal charging circuit failure
- Faulty motherboard
- Severe battery degradation
They can guide you through advanced diagnostics or arrange a repair.
