At first I wss hoping you mrant vacuum tubes. Nothing better than retro tech.

But if you mean those disgusting things meant to clean carpets, they are a fiat joke. Carpets (made of petroleum products and plastics) were a horrible idea when they were invented, extremely unsanitary. Far better to use rugs, which can be cleaned properly, along with the floor beneath them. A well woven rug will outlast a carpet.

Then along came an imperfect fiat solution to a fiat problem - the vacuum cleaner. Sure, similar devices had been used in industrial settings, but the home version wasn't nearly as powerful, and had a new purpose - to clean carpets. Industrial models were more likely to be used on hard surfaces or tight spaces. Drawing air across a hard surface is far different than drawing air through a carpet.

Also, industrial applications had a far different exhaust system, typically outside. Home vacuums either had poorly filtered exhausts, allowing dust to come right back out, or restrictive exhausts that killed any airflow. Vacuum cleaners work generating airflow, rather than producing vacuum. Dust and dirt remain stationary in a vacuum.

Early home vacuums just exhausted into a cloth bag, which meant any particulate that could permeate the cloth generally did. Bags would actually clog with dust (which is mostly dead skin cells and organic material, especially what is in home carpet), and can be quite sticky. So clogged bags killed off airflow (clogged exhaust), and the paper filter bag inserts showed up, to make the coth bags easier to clean. The paper inserts just clogged faster, killing airflow quicker, but enough lint managed to get trapped in there to convince housewifes thst something was getting clean, while most of the dust was just getting pushed down through the carpet to sit between the carpet and the hard floor, which causes wear to the floor...

Not much has changed. The basic physics will show you that cleaning dust and dirt out of a carpet is extremely hard, and it is much more sanitary to have hard floors that can be cleaned much more easily.

So, any vacuum maxis want to go a couple rounds?
