I can't speak for the Electrolux Velocity, but the Eureka Altima was fairly popular for a short time here in the USA. It became less popular when people found out how bad it was.
I have owned two Altimas. The first one was red and it was a trash pick. I hated it so much that I threw it back into the trash. I now have a yellow one that will be going to a buddy of mine who likes Eureka. As for my YouTube channel, I just renamed it to LuxDude2003 Vacuums. I'll leave a link to it.
And also I've notest that some Electrolux Velocitys have rectangle switches and some have round switches. I think thats the same with the Eureka Altima.
I don't know what else you also had under the Electrolux brand but here in the americas we also had the Eureka Contour line which are basically the bagged versions of the bagless Altimas.
