Operating Instructions
Once the new filters are correctly installed, your vacuum cleaner is ready for operation. The filters work to capture dust, allergens, and other particles, ensuring efficient cleaning and improved air quality. No special operating procedures are required beyond normal vacuum use after filter replacement.
Maintenance
Regular cleaning and timely replacement of your filters are essential for maintaining optimal vacuum performance and extending the life of your appliance.
Cleaning the Filters:
- Remove Filters: Follow steps 1-3 from the "Setup and Installation" section to remove the foam and felt filters.
- Rinse: Rinse the filters under running water until the water runs clear. Gently squeeze out excess water.
- Air Dry: Allow the filters to air dry completely for at least 24 hours before reinstalling. Do not use a dryer or other heating elements, as this can damage the filter material.

Replacement Schedule:
- It is recommended to clean the foam and felt filters after every 3-4 uses.
- Replace the foam and felt filters every 3-4 months, or more frequently depending on usage and household conditions (e.g., pets, high dust levels).
- The post-motor filter should also be checked regularly and replaced as needed, typically every 6-12 months.
Timely replacement helps reduce dust, odor, lint, and pollen, improving air quality and maintaining strong suction power.
Troubleshooting
- Reduced Suction:
- Check if filters are dirty. Clean or replace them as per the maintenance schedule.
- Ensure filters are completely dry before reinstallation.
- Verify that all filters are correctly seated in their housings.
- Unusual Odors:
- Filters may be dirty or not fully dry. Clean and thoroughly dry filters.
- Consider replacing filters if odors persist after cleaning.
- Filters Don't Fit:
- Double-check your vacuum model number against the compatibility list.
- Ensure you are installing the correct filter type (foam, felt, post-motor) in the correct location.
