Before using Roomba® for the first time, you must remove the battery pull tab and charge it overnight. Charging time under normal conditions is at least two (2) hours.
Note: If you have a Lithium Ion (Li-Ion) battery, place Roomba® on the Home Base® to wake up your robot, and then use right away. Visit Battery Types to determine which type of battery you have.
Behaviors
Roomba® should charge in the following manner:
-
If you are using a charger, the charger should have a solid green power indicator when it is plugged into an outlet.
-
If you are using a Home Base®, the power indicator should blink approximately once every four (4) seconds when plugged into the charger or outlet. For some Home Bases®, the power indicator will go out after four (4) seconds. This is normal behavior, which is designed to conserve energy.
-
On some robots, the CLEAN indicator should pulse red/amber while charging. Other robots will turn off all indicators after one (1) minute of charging, and will continue to charge. Some Home Bases® will have a solid green power indicator while charging, and others will turn off after four (4) seconds. These are normal behaviors, which are designed to conserve energy.
-
If Roomba® senses that its battery has been discharged, it will enter a special refresh charge cycle. When the refresh charge is initiated, the CLEAN indicator will quickly pulse red/amber. Do not interrupt the cycle once it has begun. The refresh charge cycle is initiated by the robot and cannot be started manually. Some robots will turn off all indicators after one (1) minute of charging in refresh charge mode and will continue to charge. This is normal behavior, which is designed to conserve energy.
Note: Refresh charge is not applicable to a Li-Ion battery.
-
When the charging cycle is complete, the CLEAN indicator on Roomba® should illuminate solid green, or will illuminate solid green after you have pressed the CLEAN button.
-
The age of the battery, room temperature, floor type, and frequency of use will reduce battery capacity over time.

Tips
-
Always store Roomba® charging on the Home Base® or with the charger plugged into the robot. For long-term storage, store Roomba® in a cool, dry place.
Note: For long-term storage of a robot with a Serial number.
- For warranty claims: Proof of purchase (receipt or invoice for purchase from an authorized retailer).
