Hi, well this is a very common european commercial power nozzle, in this specific case it hasn't been made by Nilfisk but by DUPRO AG, a swiss company that I couldn't find anymore but as many other companies use that type of pn for canisters and 2motor uprights over here I think there must be a factory very close to me... and as I have another pn like that, which is literally loosing all the blades of the cooling fan making it very noisy, I'm going to try and locate a dealer.
However US nilfisks had a household pn system that included electrified hose, wands and an "eureka" pn, we never had anything like that, a nilfisk canister with pn has got to be PERMANENTLY with pn cause the power cord runs around the wands and the hose to attach to the moto unit....
However i love Nilfisks... It takes less to use a SEBO FOR CARPET CLEANING THAN TRANSFORMING THE GM 90 !!!!
