Battery Storage and Charging
TIP: For best performance, charge Roomba’s battery overnight before using
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,
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 power supply, 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 power supply or Home Base 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.
