If your Roomba hasn't been making it home every night, he's not cheating on you; he's just tired. Breathe new life into your little buddy with a fresh battery!

Symptoms of a worn-out Roomba battery include:

Roomba repeatedly failing to return to the charging dock
Roomba found dead across the house
Roomba forgetting schedule
Roomba just not being himself

Thanks to the gifted engineers at iRobot, Roomba battery replacement requires only a screwdriver and about 5 minutes of your time. This guide will teach you how to do it.

Note: This guide will work for any 500, 600, 700, 800, or 900 series Roomba.

Place the Roomba on its back and fully loosen the four (4) bottom screws. Don't remove them completely; they're permanently attached to the cover.

Then, remove the one (1) spinning brush screw and pop the brush off.

Finally, remove the bottom cover.

There are two tabs on the old battery. Lift on them to pull the battery out of its housing.

The new battery should be identical to the old one. Drop it in place.

As always, reassembly is the reverse of disassembly. While you're at it, go ahead and replace the spinning brush. Some replacement battery kits, like this one, come with an extra brush. If yours didn't, you can grab one on Amazon for a few bucks.
