F.A.Q.s

Q. The Home Base light is on, but the robot is not charging- what to do?

It could be an issue with the Roomba’s charging connectors or the caster wheel. Clean both and ensure they are free of debris.

Q. How to charge Roomba without the home base?

Unfortunately, there is no way to charge Roomba without a home base.

But, If your Roomba has a charging jack on the side, you can charge it using an iRobot charging power supply without a home base.

Q. How to know if your Roomba is charging?

When the Roomba returns to the home base station, a battery icon will appear on the iRobot vacuum, and the charging light on the dock station will also illuminate. Still, it may turn off due to a power-saving feature.

Keep in mind that not all the Roomba models work similarly. In some models, the power light blinks for a few seconds after plugging in and then stops. In others, like the i3 and i7 series, their light indicators are off when charging, which is perfectly fine.

However, I’ve created a table to share the battery status indicator for every Roomba model to keep things simple and helpful.

The top of this table will have older models like the Roomba 500 or 600, while the bottom will have more recent models like the i3 and i7:

Model Charging Partially charged Fully charged
Roomba 500 series Amber Pulse Amber Green
Roomba 600 series Amber Pulse Amber Green
Roomba 700 series Amber Pulse None Green
Roomba 800 series Amber Pulse None Green
Roomba 900 series Amber Pulse None Green
i3 and i3+ Blinking white ….. White
i7 and i7+ Blinking white ….. White

Q. The charger light on my Roomba won’t stay on- what could be causing this?

Like other electronics, Roomba provides feedback to the user when charging. If you don’t come back after a specific time, you won’t know.

This is true for the Roomba charging point, but if your charger has the energy-saving feature turned on, the light that displays everything is working will turn off after 4 seconds.

You can observe the battery status by pushing the “CLEAN” button to see if your Roomba is charging correctly. The level will show that the device is receiving power correctly.
