I use a box fan to help dry the dishes in the dishwasher. Recently I mistakenly pointed the fan away from the dishes instead of toward them. This appears to be faster and more effective than my normal method. Why?

While vacuum cleaners might feel like a modern invention, their roots can actually be traced back to the 1800s. Specifically, in 1860, Daniel Hess of West Union, Iowa, invented a device he called a “carpet sweeper.” The apparatus used a combination of bellows for suction and a rotating brush for gathering dust. And while yes if all you have is a hard wood floors the need for a vacuum is diminished but is still helpful. And what is useless for one person is helpful to another. Now there is interesting stories on how the Dyson came around to sell such an expensive vacuum.
The carpet sweeper is an excellent example. I’ve used them and they’re great. This is exactly my point: my contention is that carpet sweepers basically solved the problem, whereas vacuum cleaners are largely a product of 20th century consumer capitalism in that they respond to a pseudo-need generated by marketing. I know that’s not a popular opinion (indeed I’m being insulted and having my comments removed just for expressing it), but I stand by it.
