Mike, I have actually adapted the plug on a Dustcare PB11 for use with the SET220 electric wand on my 2007 Miele S5280 Callisto. It's very easy to do, just spread the prongs apart with your fingers a little bit. If your fingers aren't that strong, though, as long as you are gentle, you can also use a pair of pliers. You could also make a adapter cord by splicing together the Filter Queen pigtail linked above with this generic Miele powerhead cord I am linking to below.
Nicholas - That is NOT a Hoover powerhead. It's actually a Centec copy of the Hoover Futura base PN that didn't have the headlight. It was a basic central vac PN for many years before it was discontinued, & Proteam used it on the Proteam CX440 canister, which was a rebadged German Fakir S250 Supertronic canister. We got it here in Canada as the Electron Gold S220 canister, but packaged with either a Samsung or Lindhaus 12 inch PN, depending on which option the vac shop selling it chose.
