6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your vacuum cleaner.
6.1 Emptying the Dust Bin
Empty the dust bin regularly, especially when it reaches the 'MAX' fill line, to maintain strong suction.

- Press the dust bin release button and remove the dust bin.
- Open the dust bin lid and empty contents into a waste bin.

6.2 Cleaning the Filters
The hygiene filter should be cleaned periodically to prevent clogging and maintain suction power.

- Carefully remove the filter assembly from the dust bin.
- Tap the filter gently over a waste bin to remove loose dust. If heavily soiled, rinse the filter under cold running water.
- Allow the filter to air dry completely for at least 24 hours before reinserting. Do not use a dryer or other heating methods.
