Thanks, Andy. I do think Tom makes a valid point that Lux uprights are not sealed and will therefore always leak some dust particles through their edges and openings. Other brands that are sealed and have height adjusters for deeper cleaning would outperform Aerus (Electrolux) cleaners based on those criteria.
That being said, I still think that given the fact the overall style of the '80s-era tanks, uprights, centrals, shampooer/polishers, and accessories (along with the '50s-era combination tools) have changed so little is a demonstration of their quality, reliability, longevity and customer satisfaction. I also think that Aerus (Electrolux) products provide ample performance for those who use and maintain them properly, add filtration as you have, regularly vacuum, periodically shampoo, and do what they can to prevent ground-in dirt and soiling.
