Dyson’s latest breakthrough – a vacuum without filters

The Dyson DC54 Cinetic vacuum cleaner

Dyson has once again set the standard with a new cyclone-based vacuum machine called the DC54 Cinetic, which is the first in the world to have no filters to wash or maintain, and which it promises will never lose suction in its lifetime.

Dyson engineers have created cyclones with flexible tips that oscillate at extremely high frequencies.

The spinning airflow agitates the tips, setting up an oscillation that prevents dust from sticking to the cyclones, keeping them clear.

The constant flexing of the Dyson Cinetic cyclone tips ensures the minute cyclones don’t block as microscopic dust passes through.  

Dyson engineers calculate that the new vacuum maintains constant suction and following a test involving 10 years’ worth of dust say performance of the machine at year 10 is the same as on day one.

“Getting rid of bags solved the frustration of my vacuum losing suction,” said inventor James Dyson.

“But washing filters – or worse – buying them, is still a nuisance. Dyson Cinetic cyclones are so efficient at separating microscopic particles that everything gets thrust into the bin, and you can forget about fussy filters.”
