Eureka Europa
was made in Sweden. Probably Vastervik. The final product from there was the Oxygen first series, and the Cyclone Power single stage bagless cylinder.
Electrolux AB made good machines then, but their planned obsolescence scheme was/is more frequent.
The Excalubur preceded the Europa, and was a Volta design, as Electrolux owned them as it does Eureka. There were two Europa designs, one having a small hepa filter on the rear exhaust. The other was identical to the Excellio which was much quieter, and had a top exhaust and mounted hepa filter.
The first series Oxygen was marketed in the UK as the Smart Vac cylinder.
I see a lot of Sharks in the trash these days. I don't even bother with them.
