Dyson scientists were determined to create vacuum cleaners with even higher suction. So they set to work developing an entirely new type of cyclone system.
They discovered that a smaller diameter cyclone gives greater centrifugal force. So they developed a way of getting 45% more suction than a Dual Cyclone vacuum and removing more dust, by dividing the air into 8 smaller cyclones.

Dyson proves no loss of suction using the IEC 60312 Cl 2.9 test standard on uprights and canister
vacuums and using a test method based on the IEC 60312 Cl 2.9 standard for the handheld.
Dyson proves no loss of suction, best average pick up, and 'overall outcleans other vacuums' using results from
IEC 60312 Cl 2.1, 2.2, 2.3, 2.8, 2.9, ASTM F608 and F558, and DTM 755— an independently conducted Dyson test.
