The Bad News First.
When we started Prolux the vacuum industry had been taken over by huge Chinese corporations who had bought out most of the US's "iconic" vacuum brands. Which meant 3 things.
1 - vacuums were mostly no longer designed by USA engineers.
2 - the vacuums were designed to be cheap and only last around 2 years (more profitable for them if they can get you to buy a new vacuum every 2 years).
3- as a result they do not clean very well either.
