Dyson technology. What makes Dyson better than the rest?
Why do I think Dyson is the best? It boils down to the overall design of the vacuum. Some vacuums have more suction than Dyson, some are lighter, some last longer; but those things alone shouldn't be the determining factor in a purchase.
The basics off all vacuums are the same. A motor that generates suction through an opening, and a container to catch what was sucked up. Then why don't some vacuums work as well? Why are some better than others? The specific details of how that happens, and overcoming the problems that come with it determines the quality of the vacuum.
Biggest problem - vacuums lose their suction (or more specifically, their airflow). In order for the air to move the dirt into the container, there has to be a strong enough continual flow of air moving. If you've ever been sucking up a shake through a straw and got a chunk of cookie stuck in the straw, that's a perfect picture of what happens to vacuums. The motor is still running, it's still making lines in the carpet, you can hear the crumbs spinning around the brush bar, but the pores in the bag or filter are getting clogged from the dust and debris, that airflow has likely decreased dramatically; which means it's not cleaning as good, or hardly at all.
No matter how strong a vacuum is, this problem has to be addressed if you are concerned about what the vacuum is releasing back into the air (you could maintain perfect suction if you had no filter or bag, but that, of course, defeats the whole purpose of cleaning). There are some vacuums with a beast of a motor that feels like its sucking up dirt from the neighbors carpet downstairs; but with a basic bag or filter, it's getting clogged up making the cleaning performance go down.
What has Dyson done to solve this problem? Root Cyclone Technology (it's in every Dyson vacuum). It's pretty simple, in the process of the air moving through the vacuum, they use cyclones that everything has to go through, and because of the angle everything enters into the cyclones at, the size of the opening, the angles of the cyclones, and the weight of the dirt coming it, it basically uses the laws of nature (gravity, centrifugal force) to pull the dirt out of the airflow so when the air hit the filter, it's able the pass right on through because the huge majority of the dust has been removed from the air. Brilliant!
It's not just the no loss of suction that makes Dyson such a great vacuum. They have been leading the way for years on features that everyone tries to copy. Things like the wand releasing as quick and easily as it does, the Dyson ball, the bin release, the ergonomic carrying handle, a five year warranty to back it all up, and much more. Those sorts of things, in addition to the Root Cyclone Technology, have been what has won many people over in retail stores across the nation. Dyson is an all around superior vacuum.
