Maintenance and care
When to change the dustbag
Change the dustbag when the colored marker in the airflow indicator fills the display.
Miele dustbags are disposable and made to be used only once. Do not attempt to reuse.
Check the airflow indicator
Place the body of the vacuum cleaner into the full upright position.
Use the On/Off button on the handle to switch the vacuum cleaner on, then select the highest suction setting.
Tip the vacuum cleaner until you can read the color marker in the indicator window. The electrobrush will be lifted up at the front.
If the color marker completely fills the indicator window, the dustbag needs to be changed.
How the airflow indicator works
The airflow indicator is designed to show when the bag is full of common household dust. It also measures the amount of air flow through the dustbag. Normal household dust is a mixture of dust, hair, carpet fluff, threads, etc.
However, if fine dust, such as drill dust, sand, plaster or flour is vacuumed, the pores of the dustbag may become blocked. The marker will indicate that the bag is "full" even though it does not look "full". The dustbag should still be changed, as the suction power is greatly reduced.
If the bag is bulging with pet fur, hair, carpet fluff, etc. the indicator may not register "full". This is because the air flow of the dustbag may still be high enough not to activate the marker to show maximum. The dustbag should still be changed.
