All other vacuums lose suction. Only Dyson Cinetic™ science doesn’t.1

The first vacuum so efficient at dust separation, there are no filters to wash or replace.
 
First we got rid of the bag. Now 22 years later the next breakthrough in 21st century vacuum technology: a vacuum with no bags to change, and now no filters to wash or replace. 
 
Pushing the boundaries of cyclone technology through relentless engineering, Dyson engineers have developed Dyson Cinetic Science™. Cinetic science was initially introduced in Canada in August of 2014 as a canister format. Now, Cinetic science has been elongated and is available as an upright variant for those who prefer to push versus pull. The machine is so efficient it doesn’t rely on a filter – making it the first vacuum that truly does not lose suction. 
 
Dyson Cinetic™ science
Smaller cyclones generate higher centrifugal forces, capturing smaller dust particles. But the tighter the cyclone, the more likely it is to get blocked. The solution? Flexible tips, engineered from a proprietary material, which vibrate 350 times a second. As the tips oscillate, dust is prevented from clogging the aperture. Dust as small as 0.5 microns is spun out of the airflow and into the bin – never clogging a filter.
 
James Dyson: “Removing the bag from a vacuum solved one hassle, but filter maintenance remained an annoying problem that needed fixing. Dyson engineers have spent six years perfecting cyclone technology to make filters obsolete. The constant flexing of Cinetic™ tips ensures the cyclones do not block as microscopic dust is spun out of the air – not trapped in a cyclone or on a filter.”  
 
Problem solvers
Other vacuums have leaky airflow seals and inefficient cyclones and, therefore, can have poor performance. Because their cyclones are not efficient enough to capture microscopic particles of dust, they must rely on a filter. Dust builds up on the filter and restricts airflow, resulting in a loss of suction over time. 
 
Testing standards associations, such as IEC, allow claims of “no loss of suction” if you are able to run less than one bin full of dust through a machine without a drop in performance. But what many don’t realize is when vacuums rely on filters, performance can quickly drop after one bin load.
 
Dyson spent 9,000 hours in real homes and in the lab to calculate vacuum usage patterns and their relation to dust pick-up. By conducting tests using the equivalent of 10 years' worth of dust, Dyson engineers have proved that Dyson Cinetic Science™ maintains constant suction, without ever changing or washing a filter.
