- Power Off: Ensure the vacuum cleaner is turned off and unplugged from any charging source before beginning.
- Locate Filter Compartment: Refer to your ROIDMI X300 Ultra user manual to identify the filter compartment, typically located near the dustbin.
- Remove Old Filter: Open the filter compartment and carefully remove the used HEPA filter. Dispose of the old filter responsibly.
- Insert New Filter: Place the new KarmoP HEPA filter into the compartment, ensuring it is seated correctly and securely. The filter should fit snugly without forcing.
- Close Compartment: Close the filter compartment cover until it clicks into place, indicating it is properly secured.
- Test: Power on your vacuum cleaner to confirm proper operation.
Note: For detailed instructions specific to your vacuum model, consult the original ROIDMI X300 Ultra user manual.
4. Maintenance and Cleaning
Regular cleaning of your HEPA filter is essential for maintaining optimal suction power and filtration efficiency. It is recommended to clean the filter after every few uses, or as needed, depending on usage frequency and debris accumulation.
- Remove Filter: Turn off and unplug the vacuum. Carefully remove the HEPA filter as described in the installation section.
- Tap to Clean: Gently tap the filter against a hard surface (e.g., a trash can) to dislodge loose dust and debris.
- Rinse with Water: If heavily soiled, rinse the filter under cool, running water. Ensure water flows through the pleated material from the clean side to the dirty side. Do not use hot water or detergents.
- Dry Completely: Allow the filter to air dry completely for at least 24 hours before reinstallation. Do not use heat sources (e.g., hair dryer, direct sunlight) to speed up drying, as this can damage the filter material. Ensure it is bone dry to prevent mold or mildew growth and damage to the vacuum.
- Reinstall: Once completely dry, reinstall the filter into your vacuum cleaner.
Replacement Recommendation: For best performance, replace the HEPA filter every 3-6 months, or sooner if you notice a decrease in suction power or if the filter appears visibly damaged or excessively clogged.
5. Troubleshooting
If you experience issues with your vacuum cleaner's performance after installing or cleaning the filter, consider the following:
- Reduced Suction:
- Check if the filter is clean and completely dry. A wet or clogged filter will restrict airflow.
- Ensure the filter is correctly installed and the compartment cover is securely closed.
- Verify that the dustbin is empty and other parts of the vacuum (e.g., hose, brush roll) are free of blockages.
- Unusual Odor:
- A damp filter can cause odors. Ensure the filter is thoroughly dry before use.
- Clean the filter and dustbin thoroughly.
- Filter Does Not Fit:
- Double-check that you have the correct filter model for your ROIDMI X300 Ultra vacuum cleaner.
- Ensure the filter is oriented correctly according to your vacuum's design.
If problems persist, consult the ROIDMI X300 Ultra vacuum cleaner's main instruction manual or contact customer support.
