Dyson tries to reinvent the vacuum cleaner…again

Dyson launched its original bagless vacuum cleaner in 1993, promising to revolutionise home cleaning by removing annoying bags while suffering no loss of suction.

Now, 50 models and 20 years later, Dyson claims to have removed another nuisance from the vacuum cleaner: the need to replace filters.

With this latest development, the only maintenance a person would need to do would be emptying the vacuum – although Dyson will probably invent a solution for that at some point in the future.

James Dyson, managing director of Dyson and inventor of the cyclonic bagless vacuum, said: “Getting rid of bags solved the frustration of my vacuum losing suction. 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.”

The company believes that its new line of Cinetic cleaners can perform ten years’ worth of vacuuming without the need to replace, or even wash, the filters. This means the machine can suck up two tonnes of dust before the filters have a nervous breakdown.

Dyson claims this is possible due to a new development that allows even smaller and more efficient cyclones.

The firm has spent over £7.5 million over six years, employing 29 engineers, to create a system that prevents its super small cyclones from getting blocked.

Alex Knox, director of engineering at Dyson, told the Guardian: "We created 50 prototypes of the material for the cyclone tips. We even experimented with cyclones made from blackcurrant jelly when researching for a material with the right flexibility and efficiency." 

Two thousand prototypes and 9,000 hours of testing later, the team were able to develop a material that is stiff enough to avoid collapsing inwards on the cyclone, but could also be used to create cones with flexible tips. 

The tips oscillate rapidly as the air is drawn through them at a great speed, shaking dust and dirt free and removing the potential for blockage. This means that even the tiniest particles or allergens can’t escape the vacuum.
