  • It’s not following the schedule.
  • It’s blinking red light constantly.
  • It stopped suddenly while cleaning.
  • Its suction power has decreased.
  • It’s not getting back to the base station.

Roomba Battery Replacement; 5 Easy and Quick Steps

Replacing a Roomba battery is as easy as emptying its dustbin. With little to no effort, you can easily replace a worn-out battery in a few minutes.

All you need to have is a screwdriver and a new battery!

When it comes to the type of battery, various Roomba Models have different batteries except for E and I series. These two models run on the same battery while others don’t. As far as the replacement technique is concerned, the method is almost the same.

Without wasting any time, let’s dig in…

Step 1: Put It Upside Down

The first step to replacing the battery is to put the Robovac upside down on a soft surface to prevent any damage. As its battery is located on the back side, you will be able to see it.

Step 2: Remove the Sweeping Brush

Now, pick a flathead screwdriver and loosen the sweeping brush screw on the edge. Remove the sweeping brush and put it aside.

Step 3: Remove the Bottom Cover

You will notice a total of five (5) screws on the backside of your iRobot Roomba Vacuum. These screws hold onto the bottom cover, and you will have to loosen them to remove the cover. Don’t try to unscrew them, as they are permanently attached to the cover.

Remove the cover and place it aside.

Step 4: Replace the Battery

Remove the old battery by either pressing the release tab or pulling the clips. Now, replace the new battery by aligning the channels and insert it securely.

Step 5: Reassemble Everything

After successfully inserting the new battery, it’s time to resemble everything. Put the bottom cover back and tighten all the screws. Reinstall the sweeping brush and tighten its screw as well.

Your robovac is all new and ready to rock with the same energy again!

This guide is for all the models, including i series, e series, s series, and 500/600/700/800 or 900 series.

Tips To Expand Your Battery’s Lifespan:

As mentioned earlier, Roomba batteries can easily last two to three years. However, if your battery deteriorated before the said period, it is probably due to your negligence in maintenance. You can not just save your battery from shutting down before its lifespan but can also increase its longevity by following a few tips.

  • Recharge the battery on time and fully charge it once every six months for excellent performance.
  • Try to clean your robovac regularly, as per your usage and floor condition.
  • Do not let any hair or debris clog inside, as it will cause the battery to function harder – which will end up exhausting it before time.
  • Keep the base station and charging port inside and away from direct sunlight.
  • Do timely maintenance.
  • If you do not intend to use it for a few weeks, switch it to the ship mode or remove the battery and store it in a cool, dry place.
