Roomba Charging Dock light goes off (is it normal?)

As Roomba is the best robot vacuum cleaner on the market, it has some unique features and functionalities.

In many models, the light on the charging dock goes off after you place the Roomba on the home base, but what does this mean?

Well, some reasons exist why this light blinks and then goes off; fortunately, none indicates something wrong with your robot vacuum cleaner.

Why does my Roomba’s charging dock light go off?

why does my roomba's dock light go off

Your Roomba’s charging dock light turns off to show that your vacuum is charging correctly. When you place your Roomba on the dock, the light will be solid green, indicating that it is charging. But after a while, the light will be turned off to save energy. If you think something is unusual, you may check Roomba’s charging status via the I-robot app.

The charging indicator will turn on as soon as it is docked on the Home Base. However, to save energy, it will turn off after a minute or so.

However, if you think the charging dock isn’t working, do the following things:

  • Check the power source: Ensure that the power source is working and that the charging dock is correctly connected to the outlet.
  • Clean the charging contacts: Clean the charging contacts on the Roomba and the charging dock with a dry cloth.
  • Reset the charging dock: Try resetting it by unplugging it for 30 seconds and then plugging it back in.

Why does the Roomba charger’s green light go off?

The green light on the Roomba charger indicates that you have charged your device up to its maximum capacity.

It will not take any more energy to reach a 100% charge. Now your Roomba is ready to be used, and there is no need for you to connect it to the charger.

Why is my Roomba’s dock light flashing red?

A flashing red light on the dock means your Roomba battery is too hot. This can happen if you leave the Roomba in direct sunlight or use it on a high-pile carpet.

In such cases, wait for the battery to cool down before you can continue using your Roomba.

Why is the Roomba home base light blinking?

A blinking light on the Roomba’s base station indicates a few different things. If the light flashes blue or green, it means that the Roomba is charging and its battery is in the process of being replenished.

However, if the light flashes red, it indicates an error with either the Roomba or the charging dock. In some cases, if the battery gets too hot, the base light may also flash red.

How to tell if my Roomba is charging?

If you’re wondering whether your Roomba is charging, there are a few things you can check. 

  • Take a look at the charging dock. Is the charging light illuminated? If so, that’s a good sign that your Roomba is charging.
  • Another way to tell is to check the battery indicator on your Roomba. If the battery is fully charged, it will be indicated with a green light. If it’s charging, the light will be amber. And if the battery is low, the light will be red.
  • You can also check your Roomba’s charging stats via iRobot Home App. 

Keep in mind not all the Roomba models work in the same way. 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

Determining whether the robot is charging or not can be challenging at times. The Roomba charger light indicators should blink green to signify that the robot is charging, as you learned after reading this article.

If you’re going to charge it with the Home Base, ensure the battery indicator is green by pressing the CLEAN button on the unit.
