6. Maintenance and Care
Regular maintenance ensures optimal performance and extends the lifespan of your Bosch vacuum cleaner.
6.1 Replacing the Dust Bag

- Switch off the vacuum cleaner and unplug it from the power outlet.
- Open the dust bag compartment cover.
- Carefully remove the full dust bag by pulling the cardboard collar. The bag's opening will automatically seal to prevent dust leakage.

- Close the dust bag compartment cover firmly until it clicks.

Your vacuum cleaner has two main filters:

- HEPA H13 Exhaust Filter: Located at the rear of the appliance. This filter is washable. Clean it under running water when visibly dirty (approximately every 6-12 months, depending on usage). Allow to dry completely for 24 hours before reinserting. Replace if damaged or if odors persist.
Always ensure the vacuum cleaner is unplugged before performing any maintenance.
