    • Remove and empty the dustbin after each cleaning cycle.
  • 2. Clean or replace filter:
    • Remove the HEPA/primary filter and tap gently to remove dust.
    • If washable, rinse with water and dry completely before reinstalling.
    • Replace the filter if it is deformed or very dirty.
  • 3. Clear suction path:
    • Inspect the suction inlet and internal channels for clogs.
    • Remove any compacted dust or foreign objects.
  • 4. Check brush height:
    • Ensure the main brush is installed correctly and the brush guard is fully closed so the brush contacts the floor properly.
  • 5. If suction remains weak:
    • The fan motor may be worn or partially blocked; consider professional cleaning or fan motor replacement.
