Regular maintenance ensures optimal performance and longevity of your Miele Triflex HX2 Pro.

Empty the dust bin regularly, ideally after each significant use, to maintain suction power. The dust bin capacity is 1.1 pounds.
- Detach the PowerUnit from the vacuum.
- Position the dust bin over a waste receptacle.
- Open the dust bin release latch and empty the contents.

The HEPA Lifetime Filter is designed to be maintenance-free. However, for optimal filtration and air hygiene, periodically check for excessive build-up and gently tap it to dislodge dust if necessary. Do not wash the filter unless specified in the full product manual.
