Vacuum has very weak suction even with a fully charged battery; motor sounds normal but debris is not picked up effectively.

Safety: Turn OFF the vacuum and remove the battery.

Restore airflow:

• Empty the dust container and clean the cyclone thoroughly.
• Remove and clean or replace the pre-motor filter and HEPA filter as per the Gorenje manual.
• Inspect the rubber seal between the dust container and main body; ensure it is seated correctly and not torn.
• Check the extension tube and joints for cracks or loose connections that could cause air leaks.

Reassemble carefully, ensuring all latches click into place, then test suction again.
