3. Operating Principles

These replacement parts do not have independent operational controls. Their function is integral to the overall operation of your Dreame vacuum cleaner. The main roller brush agitates and sweeps debris from surfaces, while the HEPA filter captures fine dust and allergens from the air exhausted by the vacuum, ensuring cleaner air output.

4. Maintenance

Regular maintenance of your vacuum cleaner's parts is essential for optimal performance and hygiene.

4.1 HEPA Filter Maintenance

• Cleaning: Tap the filter gently over a trash can to remove loose dust. For a deeper clean, rinse the filter under cold running water. Ensure it is completely dry before re-installing to prevent mold growth and damage to the vacuum.
• Replacement: It is recommended to replace the HEPA filter every 3-6 months, or more frequently if the vacuum is used heavily or in dusty environments, or if you notice a decrease in suction power.

4.2 Main Roller Brush Maintenance

• Cleaning: Regularly check the roller brush for tangled hair, threads, and other debris. Use scissors or a brush cleaning tool to carefully cut and remove any obstructions.
• Replacement: Replace the main roller brush if bristles become excessively worn, damaged, or if the brush no longer effectively picks up debris. The lifespan of the brush depends on usage and floor types.

5. Troubleshooting

If you experience issues with your vacuum cleaner after replacing parts, consider the following:

• Reduced Suction Power:
  • Check if the HEPA filter is clogged. Clean or replace it if necessary.
  • Ensure the filter is installed correctly and the dustbin is properly sealed.
• Poor Cleaning Performance:
  • Inspect the main roller brush for tangles or wear. Clean or replace the brush.
  • Verify the roller brush is installed correctly and rotates freely.
• Unusual Noises:
  • Check the roller brush for any foreign objects or damage. Remove obstructions or replace the brush if damaged.
  • Ensure all parts are securely installed.

• Spare Parts: Consider keeping a spare set of filters and roller brushes on hand to ensure continuous optimal performance of your vacuum cleaner.
