Charging on the Home Base®
At the end of a cleaning job or when the battery is running low, it returns to the Home Base® to recharge. When it has docked successfully, the Home Base® power indicator illuminates solid green for approximately 4 seconds, and the 
battery indicator on the robot begins pulsing to signal that it is charging.
Note: Sometimes it can take up to 30 seconds for the robot to wake up if it has been deeply discharged.
-
If Roomba® is returning to recharge after completing a cleaning cycle, it will play a series of tones to indicate successful completion of the cleaning cycle.
-
Within a minute of docking, all indicators will turn off. Roomba does this to conserve energy while charging.
-
You can check the status of the battery by pressing CLEAN once.
-
If Roomba® is returning to recharge in the middle of a cleaning cycle, it will not play a tone as it docks, and its CLEAN button will pulse with the battery indicator. The iRobot® HOME App will also display the robot's current status.
If desired, you can also send Roomba® to its Home Base manually by pressing 
Dock on Roomba® or by pressing CLEAN on the main screen of the iRobot® HOME App and then ending the job.
Note:
-
If you pick up Roomba® and manually move it to another location, it may have difficulty finding its Home Base®. For best results, allow Roomba® to complete its cleaning cycle without interruption.
-
If Roomba® appears to have trouble docking, please refer to positioning the Home Base to ensure the Home Base® has been installed in an optimal location.
-
Roomba® won’t leave the Home Base® for a cleaning cycle if its bin is full. In this case, remove and empty the bin, then reinsert it before starting or resuming a cleaning cycle (see Bin Care Procedure for instructions).
Charging
Store Roomba® on the Home Base so it’s always charged and ready to clean when you need it. Charging time under normal conditions is at least 2 hours. For best results, use only the iRobot® Lithium Ion Battery that comes with Roomba. Visit Unauthorized resellers and counterfeit products for additional details.
iRobot® HOME App Battery Status
You can easily check the status of the battery in the iRobot® HOME App.
-
A battery icon will be displayed in the top-right corner, indicating the current status of the battery.
-
The CLEAN screen will display “Ready to clean. Charging,” indicating that the battery is not yet fully charged. Roomba may run shorter than expected.
-
The CLEAN screen will display “Ready to clean. Fully charged,” indicating that the battery is fully charged. Roomba® is ready to perform a cleaning cycle.
Battery Storage
When not using Roomba® for a long period of time, Store Roomba with the battery still installed in a cool, dry place.
Reduced Power Standby Mode
Roomba consumes a small amount of power any time it is on the Home Base to ensure that it is ready for its next cleaning job as well as to maintain Wi-Fi connectivity. It is possible to put Roomba® in a further-reduced power state when not in use. For instructions and more details on this Reduced Power Standby Mode, refer to the iRobot® HOME App and navigate to
