A Brief History Of Computer Vacuums
While the name has a modern connotation, computer vacuums are actually based partly on technology developed more than a century ago.
The mechanical carpet sweeper, patented in 1876 by Melville Bissell, is considered the earliest ancestor of today's computer vacuums. When pushed, roller brushes inside the entirely man-powered sweeper would kick up dirt from the floor and direct it inside a container. The New York-born entrepreneur died of pneumonia in 1889, but his name lives on in the company he founded, which is now among the largest vacuum manufacturers in the world.
Introduced in 1900, the first powered cleaners were massive, ungainly industrial models that pushed air into a dust collector. Powered by an internal combustion engine, one of these cleaners had to be transported by horse-drawn wagon.
Powered suction vacuum cleaners, which pulled air rather than pushed it, were invented separately in 1901 by the British engineer Hubert Cecil Booth and American inventor David T. Kenney. Booth was the first to call his cleaning device a "vacuum cleaner." Still, like their predecessors, both vacuums were enormous, and impractical for private use. Kenney's even required a 2,000 pound steam engine for power.
British manufacturer Walter Griffiths invented the first truly portable vacuum cleaner in 1905. Called "Griffith's Improved Vacuum Apparatus for Removing Dust from Carpets," it was the first device suitable for domestic use. Easy to store and clean, Griffiths' vacuum called for the operator to contract a bellows to suck up air.
Though no modern company bears his name, the first portable electric vacuum cleaner was invented by American department store janitor James Murray Spangler in 1907. Spangler's creation paired the rolling brush of carpet sweepers with vacuum suction that pulled debris into a pillow case. Unable to bring his invention to market, Spangler sold the patent to leather goods manufacturer William Henry Hoover, whose name is now synonymous with the vacuum cleaner.
When The Hoover Company released the Model O in 1908, the market for domestic vacuum cleaners was ignited. Selling for $60, the Model O was the first in a line of upright suction sweepers that continues today.
As the market grew after World War II, companies worked to improve their vacuum cleaners, and many specialized models were introduced, including the first rechargeable hand-held models, which were popularized in the 1980s and 90s.
These hand-held models were further refined as the PC grew in popularity, eventually becoming the specialty computer vacuum.
How Do Vacuum Cleaners Work?
Suction is the key to vacuum cleaner operation.
Suction is generated when the pressure outside the vacuum is greater than the pressure inside. This negative pressure effect is created by an electric fan, which pulls air out of the cleaner. When the head of the vacuum rolls over the floor, the pressure difference forces air and dirt into the hose.
Because it is mixed with dust from the ground, this air can contain dangerous contaminants. For this reason, filters are critical to the safe operation of a vacuum cleaner. It is important to read the documentation included with a new vacuum cleaner, as it indicates best practices for filter maintenance. With proper care, today's vacuum cleaners are safe and effective, and can even be used to eradicate fleas.
Many upright vacuum cleaners filter air through a disposable fabric or paper bag, which allows air and little else to escape.
Unlike standard household models, most computer vacuums store the debris they collect inside a reusable compartment. This compartment can either be detached from the cleaner or opened for debris removal and cleaning. They share this quality with much larger wet/dry vacuum cleaners, which also feature reusable containers.
Take special care when using a computer vacuum on more than peripherals, because all vacuums generate static electricity. It is important to make certain the vacuum you will use features anti-static technology. Otherwise, you risk damaging the internal components essential to your machine's operation.
With any vacuum, it is possible to damage items on the floor or cause an electrical hazard by sucking up wires or operating on a wet surface. Be aware of your surroundings, and remove any cables, cords, wires, and property at risk of being damaged.
Vacuum Cleaner Design and Precautions
While popular in the United States, upright vacuum cleaners are actually rare in much of Europe. Mainland Europe favors the wheeled canister design, which separates the dust collector from the motor. Known in the United Kingdom as the cylinder model, this canister design is considered just as effective at cleaning as the upright models preferred in America.
However, thanks to a flexible hose, canister models are often more maneuverable than upright models. Many commercial drum vacuums borrow heavily from the canister design for this reason. Larger drum models can store more 50 gallons.
In commercial applications where liquid waste is anticipated, there is the wet/dry vacuum cleaner, a variation of the drum model designed to handle wet and dry debris.
Another popular model in commercial settings is the backpack vacuum, which is regarded as the nimblest of the heavy duty cleaners.
Other contemporary designs are the robotic vacuum, the portable cyclonic vacuum brought to market by British inventor James Dyson, the central vacuum system built into larger buildings, and the vehicle-mounted vacuum truck.
Due to widespread carpeting, portable vacuums like the upright and the canister are significantly more popular in the West.
Today's hand-held vacuum cleaners are often battery-powered, and feature reusable debris containers. The computer vacuum, a specialized version of the hand-held model, frequently boasts bristles and other exchangeable tips that make cleaning inside crevices and around computer keys easy.
