When to replace a Roomba battery?

An iRobot Roomba robot vacuum works wirelessly. It is equipped with a powerful battery, which is charged at the base station. Like many other cordless vacuum cleaners, the battery will eventually need to be replaced.

You may notice that the Roomba battery needs to be replaced due to the following (possible) problems:

  • The Roomba is lasting less and less
  • The suction power is greatly reduced
  • Roomba keeps shining a red light

Note: a red light does not always mean that the battery needs to be replaced. Read more about a Roomba with a red light here.

Can you postpone battery replacement?

I often get the question whether it is possible to extend the battery life. Although a battery will decrease in power anyway, there are some points with which the battery will probably last a lot longer.

If you regularly maintain a Roomba, replacing brushes in time and emptying the dust container for example, the battery will last longer than if you do this too little. For example, the vacuum cleaner has to work less hard when the dust container is less full than when it is constantly full.

If you maintain a Roomba regularly, replacing brushes in time and emptying the dust container for example, the battery will last longer

Below are some tips to potentially extend the battery life:

  • Empty the robot vacuum cleaner on time (rather too often than too little)
  • Replace parts in time, think of brushes or filters
  • Keep the filters of the robot vacuum cleaner clean

In the iRobot app you can see exactly when parts need to be replaced under the heading ‘Robot Health’. I’ve written a comprehensive guide to cleaning a Roomba. It is advisable to take a look there for a complete step-by-step plan.
