If the battery is not lasting as long as when you first set up the robot, check to see your robot’s charging status in the app. If the battery isn’t filling up all the way, visit (or return to) this article:
Why does my Roomba® not turn on or charge?If your robot produces an error message when charging, consult the
charging error messages chart.Runtime depends upon
battery type. Visit the
battery compatibility chart for more battery information, including runtime per cleaning job.
Review the
battery maintenance tips to make sure that you are taking proper care of your battery.
If you are experiencing poor coverage, the robot isn’t cleaning where you want it to, or if you are trying to clean a specific room or area, please use the following information to improve performance.
- Make sure that nothing is blocking the robot from driving off the Home Base.
- Nothing should be blocking the path you want the robot to clean.
- Ensure that the battery is fully charged based on the light ring and battery percentage in the app.
- Confirm that you have the latest robot software version installed.
- For Braava®
- The correct pad is installed for how you want to clean.
- The tank is completely full of water and optional iRobot Hard Floor Cleaning Solution.
If you believe that your robot should be running longer than it is and you have followed all of the steps above, try testing the batteries’ runtime.
Testing the battery runtime on Roomba® or Braava®
- Make sure that the battery is fully charged by leaving the robot on the base for a few hours or until the app tells you that it’s fully charged.
- Unplug the Home Base/Clean Base® from the plug socket and put it away for this test.
- Press the CLEAN/cleaning button to run your robot
- Track the time it takes for the robot to end its mission with either an “I’m done” tone, a 4-tone dead battery song or a “Low Battery Please Charge” message. You may need to run several cleaning jobs to fully drain the battery.
NOTE: Try to keep the Roomba® on hardwood floors for this test. You can expect a shorter runtime on carpets.
Interpreting the results
- e series Roomba® should run for at least 90 minutes
- 900, i, j, s and m series Roomba® should run for at least 75 minutes
- 400–800 series Roomba® should run for 60 minutes
If your robot stops with a low battery error before meeting the minimum times listed above, consider replacing your Robot’s battery. Visit the
iRobot Store – Parts and Accessories to order a part.
If you believe that your robot is within warranty, please contact
