Using the Universal Floorhead
The universal floorhead is suitable for both carpets and hard floors. A foot switch on the floorhead allows you to retract or extend the brush bristles. Extend bristles for hard floors to prevent scratching and retract them for carpets to allow deeper cleaning.

Using Integrated Accessories
The dusting brush, corner brush (crevice nozzle), and upholstery nozzle are conveniently stored within the vacuum cleaner's body. Open the accessory compartment to access them. These tools are designed for specific cleaning tasks:
- Dusting brush: For delicate surfaces, shelves, and ornaments.

Comfort Park System
For quick breaks during cleaning, the Comfort Park System allows you to hook the floorhead onto the side of the vacuum cleaner. This holds the suction tube in an upright position, making it easy to pause and resume cleaning.

Maintenance
Replacing the Dust Bag
The dust bag should be replaced when the dust bag change indicator illuminates or when suction power noticeably decreases. Always use genuine Miele HyClean dust bags for optimal filtration and performance.
- Switch off and unplug the vacuum cleaner.
- Open the dust compartment lid.
- The dust bag collar will automatically close when lifted, preventing dust escape. Remove the full dust bag.
- Insert a new HyClean dust bag, ensuring it sits correctly in the holder.
- Close the dust compartment lid until it clicks.

Replacing the HEPA Filter
The HEPA AirClean filter (SF-HA 50) is designed to capture fine dust and allergens, making it ideal for allergy sufferers. It should be replaced approximately once a year, or when the filter change indicator (if present) signals. Always use genuine Miele HEPA filters.
- Switch off and unplug the vacuum cleaner.
- Locate the filter compartment, usually at the rear or top of the vacuum cleaner.
- Open the filter compartment and remove the old HEPA filter.
- Insert the new HEPA filter, ensuring it is correctly seated.
- Close the filter compartment.

Motor Filter Maintenance
The motor filter protects the motor from dust. It is typically located behind the dust bag compartment. Check its condition when changing the dust bag. Replace it if it appears heavily soiled or damaged. The motor filter usually needs replacement after every 4-5 dust bag changes.
