Maintenance
Regular maintenance of your replacement parts is essential for prolonging their lifespan and ensuring consistent cleaning efficiency.
HEPA Filter Maintenance
- Cleaning: Tap the filter gently over a trash can to remove loose dust and debris. For deeper cleaning, rinse the filter under cool running water. Ensure the filter is completely dry before reinstalling it into the vacuum cleaner.
- Replacement Frequency: It is recommended to replace the HEPA filter every 3 to 6 months, depending on usage and household dust levels, to maintain optimal filtration performance.
Main Roller Brush Maintenance
- Cleaning: Regularly inspect the main roller brush for tangled hair, threads, or debris. Use the provided cleaning tool (refer to Figure 1) to cut and remove any entangled material from the brush bristles.
- Replacement Frequency: The main roller brush should be replaced every 6 to 12 months, or sooner if visible wear or damage affects cleaning performance.
Troubleshooting
If you experience issues after installing the replacement parts, consider the following common troubleshooting steps:
- Reduced Suction:
- Check if the HEPA filter is clogged. Clean or replace it as per maintenance instructions.
- Ensure the dustbin is empty and properly seated.
- Brush Not Spinning or Ineffective Cleaning:
- Inspect the main roller brush for tangled hair or debris that might be obstructing its rotation. Clean thoroughly using the provided tool.
- Verify that the brush is correctly installed and the brush cover is securely closed.
- Unusual Noises:
- Ensure all parts, especially the brushes and filters, are correctly installed and not loose.
- Check for any foreign objects lodged in the brush roll area or air pathways.
