Battery Storage and Charging
TIP: For best performance, charge Roomba’s battery overnight before using
Roomba for the first time. Always leave the battery inside Roomba with
Roomba plugged in or on the Home Base.
Roomba is powered by a rechargeable battery. Roomba’s battery can last
for hundreds of cleaning cycles before a replacement is necessary.
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.
TIP: If Roomba’s battery is warm, Roomba will wait for the battery to cool down
before beginning a charge cycle.
TIP: For long-term storage, iRobot recommends that the battery be fully
charged and then removed from the robot and stored 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 Home Base/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 light will pulse quickly. Note: For
best results, do not interrupt this Refresh Charge.
