Possible Causes

Aged lithium-ion battery with reduced capacity, Battery not fully charging due to dock contact issue, High suction mode draining battery quickly, Battery temperature sensor drift

How to Fix / Troubleshooting

Safety first: Do not continue to operate a battery that becomes excessively hot or swollen.

  • 1. Clean charging contacts: Wipe the robot and dock contacts to ensure efficient charging.
  • 2. Full charge cycle: Leave the robot on the dock for at least 4–5 hours, then start a cleaning cycle and time the runtime.
  • 3. Adjust cleaning mode: Set suction to a standard or eco mode and retest runtime to rule out heavy-load operation.
  • 4. Battery replacement: If runtime remains significantly below specification, replace the Electrolux battery pack with a genuine replacement.
  • 5. If issue persists with new battery: The charging circuit or battery sensing on the main PCB may be faulty and require professional service.
