Who is James Dyson? James Dyson was a successful inventor, he owned a factory in the West Country in England where he manufactured his own plastic garden equipment. He was an artist by trade and was always playing around with ordinary designs to make them extra-ordinary.
His factory was constantly plagued with dust, so he designed a “cyclonic” air filtering device to keep it clean. His machine proved to be an extremely efficient design, which set him on the path to creating the Dyson vacuum cleaner we have today.
The Dyson Vacuum Design
The principle he used for his machine was the same as the principle used in a washing machine to spin clothes at the end of a wash cycle. In the washing machine, the clothes are flung against the edge of the drum at high speed, which forces the water out through the tiny holes in the drum. James Dyson used the same idea in the air filters in his design and they proved to be just as effective. He found that spinning separated the heavy dust particles from the dirty air which could then be trapped and collected, the clean air would then be piped back into the room.
Basic Vacuum Cleaners
The basic vacuum cleaner sucks dirty air in and blows it directly into the vacuum bag, the bag catches the dirty air and the clean but ‘dusty‘ air drifts back into the room. The vacuum bag fills up the longer the vacuum cleaner is used, which means that the empty air capacity is decreased, diminishing its ability to suck in more dirt. The problem can get worse if the bag isn’t emptied often, more dust and dirt in the bag, means more dust will escape when emptying it.
James Dyson felt his design could improve this problem, though he didn’t actually invent the idea of using a cyclone to remove dust from the air. This was an earlier invention, which was developed 70 years before in 1913 and patented in 1917 by Bert. M. Kent, which he called a ‘Vacuum Creating and Dust Separating Machine’ What Dyson’s did, was to apply this principle to a more compact, vacuum cleaner ideal for the ordinary household.
Launching the Dyson
He perfected his invention between the late 1970’s and the mid 1980’s building well over 5,000 prototypes of his cyclonic cleaner. He designed a bright pink cyclonic vacuum cleaner called the G-Force in the late 1980’s and sold it in Japan. Although it was a large, clumsy and expensive cleaner, it earned him enough money to develop a compact, more affordable cyclonic vacuum cleaner called the DC01. This new machine won numerous design awards in the mid 1990’s and it wasn’t long before it became Britain’s biggest selling vacuum cleaner.
How Does a Dyson Work?
Unlike the basic vacuum cleaner, which has heavy exposed motors with lots of parts that will break or wear, the Dyson vacuum cleaner is quite simple. The machine has a well hidden motor inside the ball at the foot of the machine, which drives a centrifugal force using ‘root cyclone’ technology.
Root cyclone is an everlasting powerful suction technology which allows the air inside the vacuum cleaner to spin at very high speeds, which results in a strong consistent suction. First the dirt and dust is gathered through a filtering system then it is sent to a bin, where the larger particles are caught and separated. Not only does this technology provide lasting suction, but as there is no bag full of dust and dirt, it also reduces the chances of the vacuum clogging. The bin on the Dyson still has to have its bin emptied every so often but because it always sucks with exactly the same power, the cyclonic action means that it will work equally as well with a full bin as well as one that has just been emptied.
What Makes it Different?
The cone shaped cyclone picks up dirt and dust with high suction and spins this debris into small particles at 900 mph. Once the dust particles have been blended, they are sent through HEPA filtered cylinders, this is where all the dirt particles are captured and contained within a single removable dust bin. Dirt and dust cannot filter out into the air and the machine doesn’t get clogged with large pieces of debris. Dyson’s vacuum cleaners are totally bag-less so there is no extra cost of purchasing bags on a regular basis.
HEPA filters are featured inside all Dyson vacuums. These filters are specially designed for each individual type of Dyson, and are made to last the entire life of the cleaner. The upper dust filter is just above the cyclone and there is another filter immediately above the dust collection bin, with another filter at the bottom of the machine. This last filter helps to give the air an extra clean before returning it to the room.
The powerful electric motor of the Dyson is effectively a giant fan that sucks air in through its cyclone and filters. The cyclone is a large yellow plastic cone that points down into the dust bin, this is the most important part of a Dyson. The electric motor sucks dirty air into the top of the cyclone along a network of tubes, where it is then pulled and whirled around at high speed, before returning back through the pipe to the bottom of the machine and expelled as clean air. While the air is drawn through the cone, the dust spins around, drops down, and collects in the clear plastic bin beneath ready for disposal.
Are Dyson Vacuums Worth it?
The answer to that is most definitely yes. James Dyson helped to change the way vacuum cleaners work and revolutionized the vacuum cleaning industry with the powerful ‘suction and ball’ technology he developed. Although there is no doubt that Dyson machines are more expensive than most of the best vacuum cleaners they are however more powerful at sucking up the dirt and debris from the floor than the normal vacuum cleaner so you can be sure that all of the dirt is removed from the carpets using a Dyson.
