Cyclonic vacuum cleaners

The 'cyclone' vacuum is a relatively new device, invented by Englishman James Dyson during the 1980's. It took some time to convince backers to provide funding, but by the mid 1990's his cyclonic Dyson's were a huge success. The two major benefits from this technology are,

1. No requirement of dirt collection bags.
2. Suction is not impaired as the bag/collection cylinder is filled.

Cyclonic vacuums like the Dyson do still use filters to remove particles which may clog the inner mechanisms. The dirt is collected by spinning air at such a force that a vortex is created. The filters ensure that clean air is expelled from the vacuum, which helps to keep the outside air free of allergens.

One of the major drawbacks of vacuums is that whilst they do pick up the majority of dust from a carpet they also cause some of the dust to be blown into the air.

This means that the operator of the vacuum, and anyone who is in the room will be breathing in quite a large amount of dust. If they suffer from allergies using a vacuum can become an uncomfortable and pose health issues.

The general principle of how a cyclone works is the belief that because dirt is literally spun out of the air it ensures less dust escapes into the atmosphere of a room.

It's therefore important to always clean the filters in a cyclonic vacuum to make sure the air taken in by the cyclone to be spun is as clean as possible.
