Battery Storage and Charging

Roomba is powered by a rechargeable battery. Roomba’s battery can last for hundreds of cleaning cycles if cared for properly.

Battery Life

To extend the battery life, iRobot recommends always storing Roomba plugged in. For more details on how to maintain Roomba’s battery life, visit www.irobot.com/support.

TIP: Recharge Roomba as soon as possible. Waiting several days to recharge Roomba can damage the battery.

TIP: For storage off the charger, remove the battery from Roomba and store in a cool, dry place.

Cleaning Time

You should fully charge Roomba’s battery before each cleaning cycle. When fully charged, Roomba’s battery will last for at least one full clean cycle.

16-Hour Refresh Charge

If Roomba has been left off the charger for an extended period, Roomba will initiate a special 16-hour charge cycle. This extensive charge refreshes Roomba’s battery and extends the battery life. While charging, Roomba’s “Clean” button will pulse quickly. Note: For best results, do not interrupt this Refresh Charge.

TIP: For best performance, charge Roomba’s battery overnight before using Roomba for the first time.
