iRobot Roomba Maintenance Manual page 2

Please take care when removing the pull tab, if it breaks you will need to follow the three st€ps below to
check nothing is blocking the battery connection points
To maintain maximum battery life, Roomba will begin a 16 hour charge cycle when the robot has been left off
the charger for an extended period of time. This may also happen the first time you charge Roomba.
Do not interrupt this 16 hour cycle.
For best performance, always store Roomba on its charging base.
With proper use and storage, Roomba will not use the 16 hour charging cycle after the first time.
Charging Roomba can be done in 2 different ways:
Directly to the power supply (bypassing the home base)
lf Roomba's battery life has shortened, you may need to reset the battery. Before the battery can be reset it
needs to be run until Roomba plays the dead battery song. To stop Roomba returning to charge after its
cleaning cycle disconnect the home base.
1. Reset the Roomba charging system. Do this by removing the battery and holding down the "clean" button
for at least 20 seconds. Then reinstall the battery.
2. Plug the charger into Roomba (avoid using the home base if you have one so as to ensure the Roombat
charging cycle is not interrupted.)
3. Charge the battery until the Roomba power light is solid green and keep the Roomba on the charger for an
additional 72 hours (3 days.) Note: Do not interrupt this charging cycle.
4. In the Max mode, run the Roomba for one complete rycle without a home base present, repeat steps 3 and 4
a few times. lf your Roomba does not have max mode, run several clean rycles until Roomba stops and plays
the 'dead battery' song.
5. N€ver store the battery inside the unit unless it is connected to the charger or charging on the home base.
For storage and transporting Roomba, fully charge and then remove the battery.
Run time varies depending on floor type, room layout, battery age and amount of debris.
Battery performance and run time will decrease over the warranty period. Maintaining clean brushes
optimizes battery performance.
