Sir James Dyson perfects vacuum cleaning by eliminating filters

World leader in vacuum cleaning technology, British inventor Sir James Dyson's Dyson Ltd claims its machines keep sucking at almost full blast even as its dirt bin gets full.

Dyson cleaners have hidden filters that need to be periodically cleaned to keep the vacuum running at full strength, gizmodo.com.au reported.

For a company that took pride in its claim of its machines never losing suction, that was something that needed fixing. So to ensure that users would not ever forget to clean those filters, Dyson simply engineered a better vacuum design that eliminated them altogether.

Thanks to cyclone technology that traps and funnels dust and dirt, Sir James was able to get rid of the traditional disposable vacuum bags decades ago. And over the years the company discovered that the smaller a cyclone one could create, the stronger the centrifugal forces it would be able to generate to help efficient capture of tiny particles and that was the reason the recent models of Dyson vacuums featured multiple smaller cyclone chambers.

However, when those cyclones got too small and too tight, they could end up clogging with dust that blocked other debris from passing - and that hindered suction.

The Independent reported that vaccum cleaner filters help filter tiny bits of dust from the air that they suck in, though the dust could build up on that filter and clog the airflow.

The new models do not lose any suction even when the bin is nearly full. The development follows an independent survey by the German Institute for Quality that revealed that Dyson was Germany's favourite vacuum cleaner despite the presence of larger brands including Miele, AEG, Bosch and Kärcher.

Dyson's new machines come with smaller cyclones, which help capture smaller dust particles, which also makes it easier to clog any filter. The company avoids the problem by using the tiny oscillating tips, which it calls Cinetic, that push dust straight into the bag.

The new machines also uses Dyson's ball technology, which feature a big sphere on the bottom and allows the machines to roll much more easily. The ball, which is much bigger than in current machines provides a lower centre of gravity, making it easier to move the machine around.
