Robot vacuum has very short runtime and returns to dock after only a few minutes of cleaning.

Safety: Turn OFF the robot and remove it from the dock.

• Full charge: Place the robot on the dock and charge uninterrupted for at least 4–5 hours until the indicator shows full.
• Run full cycle: Start a cleaning cycle and allow the robot to run until it returns to the dock by itself. Note the runtime.
• Repeat once: Perform one more full charge/discharge cycle to recalibrate the battery gauge.
• If runtime remains poor: Replace the Li-ion battery pack with an AEG-approved replacement. Dispose of the old battery according to local regulations.
