My Miele C3 was originally the straight suction model. So it didn't have any capabilities to take even the Miele powerhead. It would have been the same process to make the connectors to the Miele powerhead.
I already had the Sebo Felix so I naturally used the Felix powerhead. I use the same powerhead in my Felix, Miele C3 and Sebo K1. Actually Sebo powerhead fits to all of my canister vacuum cleaners what have with the powerhead wiring.
I just love the Sebo ET1 ph. I have never used the full size Miele ph
