We are witnessing this generations' Renaissance. I remember when the Ren was released although I was still a kid and not quite aware of the internals of a vacuum. I experienced a Ren in an Electrolux store. I thought it's suction was incredible at the time. The Ren was easily the most advanced machine on the market during it's (admittedly brief) time. It's a shame they couldn't continue on with that amount of high tech features. The Platinum is now a technological marvel of it's own. And Aerus and Lux have patented the double HEPA technology so it cannot be copied for 20 years. Electrolux's proprietary automatic shut off technology still has not been copied, even after 50 some years. We are talking about Aerus being "back" but they never really left. I roundly criticized Aerus for steadily stripping the high end features from thier machines with each successive model after the Renaissance. However, the Ultra was not an obsolete vacuum. It was a comedown from the previous few models, but it wasn't a "bad" vacuum. The Platinum has generated excitement, which is great for Aerus. It's exciting for those of us who stood by Aerus during it's name change debacle.
