My 2 Cents
As far as the housewives in the old advertisements, seen enjoying their appliance with an unnatural passion, one has to consider the fact that these companies were trying to sell it. Naturally, they're going to make their models look overjoyed with the product.
Whether or not women loved their vacuums in reality, I do not know.
But if we consider what they were likely using before their new fancy electric vacuums, loud, cumbersome,unaffordable, more primitive models, or worse- a BROOM, well I'd probably think that new Electralux XXX that Santa left under the tree was a dream come true.
