This is an adapter that makes it possible to connect any Festool machine (for example Festool Rotex RO90 sander) to a Kärcher (for example WD20) vacuum cleaner. The adapter makes it possible to connect a D27 x 3.5m CT antistatic Festool hose to the Kärcher WD20 or A2004 (other Kärcher vacuum cleaners probably also fit). A better solution with dust collection than none at all.
