Frequently Asked Questions
Why did my Miele vacuum suddenly lose suction with a new bag?
If suction is lost immediately after fitting a new bag, check that the bag collar is seated correctly in the bag compartment. An unseated bag prevents suction from developing.
Can I use non-Miele bags in my Miele vacuum?
Non-genuine bags often fit but have looser tolerances and poor filtration. They can also cause false low-suction symptoms. Use genuine Miele bags for best performance.
How do I know when my Miele bag is full?
The red bag indicator light will illuminate, or the needle on the analogue gauge will move into the red zone. Replace the bag promptly to maintain suction.
