Although it was already there in the accessory box of my Miele vacuum cleaner, I immediately have bought the Miele SSP 10 Saugpinsel as a substitute, because that part is awesome. I now wipe dust with a damp rag less, but brush and suck it right away :-) Especially electrical appliances with its many edges and knobs are therefore get super dust-free and has no more fear that inadvertently, two splashes of water can pass through the ventilation slots into the electronics inside. Even if the wet cloth was wrung, the fear is always there.
