why did they invent the vacuum cleaner?

Answer 1

After the war the US government needed to keep the factories running and the workers still in jobs. They didn't need guns and tanks so much so they quickly got the factories converted to turn out things that the public might buy. Like the vacuum cleaner.

In the beginning to recoup development costs and due to monopolies created by patent protections and prices fall as more and more products are sold and more manufacturers come on line). You might guess that the reason vacuums were such a great hit was because they were such a time saver, but this isn't the case. Vacuums and thousands of other new products were rushed to market and cheaply sold right after WWII in order to keep the economy rolling and protect manufacturing jobs. Millions of women had taken factory jobs to support the war, and with no more need for tanks and guns, the factories quickly retooled and turned out things like vacuum cleaners, thereby eliminating wholesale layoffs of the American workforce - which could have sent the US economy into a tailspin. America ran its largest deficit in history to finance the war and needed workers to continue to draw paychecks and pay taxes to pay down the debt. The government did this by selling them products they wanted - and in many cases the products were products they themselves had assembled. It took brooms 30 years to make a comeback, which they accomplished with the invention of the angled brush.

Answer 2

The vacuum cleaner was invented to remove dirt and it's mostly used in homes as well as in industry.
