How to Fix Roomba Charging Error 8

Your Roomba’s “charging error 8” status indicates a problem with the device’s battery or charging system known as a “communication fault”. Put simply your vacuum is not getting a proper signal from the charger when it docks.

 To fix this issue, you can try the following steps:

Check and Clean Connections

1. Ensure the battery is properly inserted and seated securely in the Roomba
2. Clean the battery contacts and the contacts in the Roomba to remove any dust and debris
3. Inspect the charging dock for visible damage or dirt on the contacts
4. Clean the charging contacts on both the dock and the Roomba to ensure a proper connection

Reset the Roomba

1. Remove the battery from the Roomba
2. Hold down the power button for 20 seconds
3. Re-insert the battery and attempt to charge it again

If that doesn’t work, you can try this reset procedure:

• While the Roomba is connected to the charger, hold the spot/target button and the dock/home button simultaneously for about 10 seconds until you hear a sound

Battery Troubleshooting

1. If the error continues, consider replacing the battery with a new, authentic iRobot lithium-ion battery
2. Ensure the Roomba is being charged at room temperature

Additional Tips

• Try lifting the Roomba from the charging station when the error occurs and reseat it multiple times
• If the Roomba has been unused for a long time, try leaving it on the charger for an extended period for the first charge.
• Run the Roomba until the battery is completely depleted, then recharge it. Repeat this process a few times if necessary
