Roomba for the first time.
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,

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.
