3. Semi-Automatic Filter Cleaning
This feature helps maintain suction by clearing dust from the HEPA filter.
- When the dust-full indicator illuminates or suction power decreases, the filter may need cleaning.
- With the vacuum running, press and hold the semi-automatic filter cleaning button (usually located on the motor head) for a few seconds.
- Release the button. The vacuum will briefly reverse airflow to dislodge dust from the filter. Repeat if necessary.
