The dyson. a great example of engineering innovation.
james dyson began inventing the dyson vacuum in 1978 after his frustration with conventional vacuum cleaners. interestingly, his idea came from an industrial application where he built a "cyclone" system in a paint factory he worked in.
a cyclonic separation is a method of removing particulates from a gas or liquid stream, without the use of filters, through centrifugal force. a centrifugal force is an inertial force directed away from the axis of rotation that appears to act on all objects when viewed in rotation.
a high speed rotating airflow is established within a cylindrical container called a cyclone. air flows in a helical pattern, from top to bottom using gravitational and rotational effects to separate particles from the air. this completely removes the need for vacuum bags and filters. examples of cyclones used in industry include wood saw mills, pharmaceutical extracts for toxic compounds and in oil refineries to separate liquids and gases.
