The aforementioned for runners of the bag-less and bagged vacuums were sold mostly door to door. That was well before television or the internet. Word of mouth sold vacuums as well as print advertisements got the prospective buyers attention. Or were sold in appliance stores where you bought your stove, refrigerator and washing machine.
Also consider that homes and farms at the time were just getting electrical power. Didn't have electric at your home at the time. There was no use for an appliance that required electricity to use it. Cities had power well before outlining areas.
