Possible Causes
Aged lithium-ion battery, frequent partial charges, high-temperature storage, internal cell imbalance.
How to Fix / Troubleshooting
Safety: Turn the robot OFF and remove from dock.
- Full charge: Place the robot on the dock and allow it to charge uninterrupted for at least 4–6 hours.
- Test runtime: Run a full cleaning cycle and time how long it operates.
- Replace battery: If runtime is significantly below the original specification (e.g., less than 20–30 minutes), replace the battery pack with a compatible Shark battery.
