Dyson launches bagless vacuum cleaner

Dyson's latest vacuum uses patented Dyson Cinetic cyclone technology. The cyclones are so efficient there is no filter maintenance: no washing, nothing to replace, one less thing to think about.

"Getting rid of bags solved the frustration of my vacuum losing suction. But washing filters - or worse - buying them, is still a nuisance," says James Dyson, founder of Dyson. "Dyson Cinetic cyclones are so efficient at separating microscopic particles that everything gets thrust into the bin, and you can forget about fussy filters."

Dyson engineers spent time in real homes to calculate how much dust would be picked up over 10 years. By using the equivalent volume of dust, the engineers proved that the Dyson Cinetic™ vacuum maintains constant suction, with ten years' worth of test dust, and no filter maintenance.

Now how exactly does the Dyson Cinetic cyclones work? Although smaller cyclones generate higher centrifugal forces to capture smaller particles, tighter cyclones are more likely to block. Dyson engineers have created cyclones with flexible tips. The spinning airflow agitates the tips, setting up an oscillation which prevents dust from sticking to the cyclones - keeping them clear.

James Dyson has proved that inventive thinking and rigorous engineering techniques produce better machines, and the company and its growing team of engineers and scientists are dedicated to inventing and improving Dyson machines. This is evident in the 50 iterations the engineers went through with this specific technology, using different materials. If the material is too hard, the tips cannot oscillate enough to move dust through to the bin. If the material is too soft, the airflow causes the cyclones to shut, blocking them off.

The vacuum cleaner also features a carbon fibre turbine head which removes dirt on carpets with its stiff nylon bristles, and fine dust from hard floors with the ultra-fine antistatic carbon fibre filaments.

Using ball technology, the Dyson Cinetic vacuum has a low centre of gravity and is easier to pull without snagging on corners or the carpet pile. Coupled with a unique central steering system, the vacuum uses an articulating chassis and central pivot point for negotiating tight turns and circumnavigating sofas.
