In my last post I told you all about how Bean and I found out about the nasty allergens floating around us that the microbiologists and clever folk at Dyson have been working out ways to banish which you can read here.
Now Dyson are reading to unveil their secret weapon to combat the dust mites and all they’re pesky poo. Here’s how, get ready and don your safety goggles…
In 1993, as we know bags were out. Twenty years of research and development later, Dyson is introducing the only machine with no bags, no loss of suction, and no filter fuss.
Bagged vacuums lose suction as pores clog. And other cyclonic vacuum cleaners often rely on filters to capture dust, which also clog, causing loss of suction. 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.
Perfect, right?
James Dyson: “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.”
Other manufacturers may claim ‘no loss of suction’, but test their machines with less than one bin-full of dust (IEC 60312-1 Clause 5.9). After just one bin load performance can start dropping. 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 they proved that the Dyson Cinetic™ vacuum maintains constant suction, with ten years’ worth of test dust, with no filter maintenance.
Dyson Cinetic™ cyclones
Smaller cyclones generate higher centrifugal forces and capture smaller particles. But the tighter the cyclone, the more likely it is 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.
Dyson engineers went through 50 iterations of the 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.

On carpets the stiff nylon bristles remove dirt. On hard floors the ultra-fine antistatic carbon fibre filaments remove fine dust.
Dyson Ball™ technology
Sitting on a ball, 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.
After learning all about what’s packed inside the Cinetic, we were given a live demonstration with another vacuum cleaner from a competitor. It was vacuums at dawn, a highly polished floor and an awful lot of finely milled baking powder – something as a mum, is funnily enough something I have had to try and clear up after some overzealous baking with a small child. Oh, and washing powder, talcum powder, flour, make up- ya know, the whole kaleidoscope of mess that gets thrown at us.
The results were impossible to deny, the generic vacuum cleaner simply moved the powder around, relying on its filters – it failed to pick up the powder. However the Dyson Cinetic picked up every particle with total ease – even a toddler did it!
