cue003 hit the nail on the head...
From Wikipedia (see link):
A meme (pron.: /ˈmiːm/; meem)[1] is "an idea, behavior or style that spreads from person to person within a culture."[2] A meme acts as a unit for carrying cultural ideas, symbols or practices, which can be transmitted from one mind to another through writing, speech, gestures, rituals or other imitable phenomena. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate and respond to selective pressures.[3]
Overall the meme has changed in the vacuum world to the disposable vac or Swiffer on hard surface flooring. 70's shag is gone along with the ability of an average person to change a belt and what's even more lacking would be knowing when to, where to get one, & is it the right one for their machine in the first place. So forget offering any design that requires the belt meme. Bags fall into this catagory now to it seems.. All most people know about DTD is it's riddled with scams & rip offs be it vacuums sold by instillment with loan shark rates or other products/charities.
I stopped fighting & have joined the crowd in as much as i'm able to say, found at the right price (not hard if you can use the internet), some of those plasti-disposable vacs offer astonishing capabilities for the money spent. Yes those with crippling allergies need not apply, but they have probably moved on to hard surface by now any way. I see a Kirby and think, "what a sweet piece of machinery, & for almost nuttin' honey!" ($50 used Sentria w/o attachments)...she thinks, "what a tank".
Bagsless is the new shakeout, today's Dyson bling is the Chicklet colors of 60's & 70's Hoovers, who's Constellation model seems most endearing to collectors, but was no doubt was cosidered a toy by serious types back in the day. Memes have changed but it can also be said, "what's old is new again"...vacuums may even be mostly made state-side again someday, stranger things have happened.
