Regular maintenance of your filter ensures optimal vacuum performance and extends the life of your appliance. The filter is washable and reusable.

- Replacement: For best results and to maintain air quality, the filter should be changed every 2-3 months, or more frequently depending on usage and the type of debris collected.
8. Troubleshooting
If you experience issues with your vacuum after filter installation, consider the following:
- Reduced Suction: Ensure the filter is clean and not clogged. A dirty filter can significantly reduce suction power. Check that the filter is properly seated and the retainer nut is tightened.
- Dust Escaping: Verify that the filter is correctly installed and sealed against the vacuum's filter cage. A loose or improperly seated filter can allow dust to bypass the filtration system.
- Unusual Noises: Check for any debris lodged in the filter or vacuum components. Ensure the filter is not damaged.
