Charging LEDs
Normal and Recovery Mode : The power LED pulses orange as long as the robot is in the
normal (slow pulse) or recovery (fast pulse) charging state. Note that this does not
necessarily mean that current is actually flowing into the battery. If the robot's hardware is
damaged such that no current can flow into the battery, the LED pulses orange until an end-
of-charge condition is detected, such as the 9 hour timeout.
Waiting/Trickle Mode : The power LED is solid green when the robot is doing post-
charge cooling and trickle charging.
Power Supply Troubleshooting
Is the Power Supply LED solid green while charging? If not try another wall socket.
If the power light is off or flashing, replace the Power Supply and test the Roomba and Home Base
for charging errors.
