Radix Cyclone™ technology

James Dyson first invented cyclone technology for vacuum cleaners 30 years ago. Ever since, Dyson engineers have been improving it, making it work better and better. As they invent, they patent – protecting their efforts from copycat manufacturers. To date, they have filed 564 patents. You won’t find Radix Cyclone™ technology in any other vacuum cleaner.

Vacuum cleaners with Radix Cyclone™ technology

All Dyson barrel, upright, compact and handheld vacuums use Radix Cyclone™ technology for no loss of suction.

Why ordinary vacuums lose suction

Ordinary vacuum cleaners, even those that don’t use bags, lose suction as they clean. Here’s why:

Bagged vacuum cleaners

The bag is meant to trap dirt and dust, and allow air to escape through millions of tiny holes in the paper. But when you start to use a bagged machine, dirt and dust collects in the bag and clogs the holes. This restricts the airflow, which causes a loss of suction, reducing the efficiency of the vacuum and leaving dust and dirt behind in your home.

Bagless vacuum cleaners

Ordinary bagless cleaners work in a similar way to those with bags. The cyclone collects the large dirt, but a central filter is still required to trap the fine dust. Just like a bag, it quickly clogs and restricts the airflow, causing a loss of suction and reducing the efficiency of the cleaner.

Why Dyson vacuums with Radix Cyclone™ technology don’t lose suction

Dyson's patented Radix Cyclone™ technology doesn't rely on a bag or filter to trap all the dirt and dust. Instead, it spins the air so fast that centrifugal forces up to 150,000 times the force of gravity fling dirt and dust out of the air and straight into the clear bin.

 

Radix Cyclone™ technology + intermediary cyclone

In our latest machines, Dyson engineers have combined Radix Cyclone™ technology with an intermediary cyclone – an extra cyclonic stage between the outer and inner cyclones – to separate particles as small as 0.5 microns from the airflow. You could fit 200 of these particles on a full stop. View all machines with Radix Cyclone™ technology + intermediary cyclone technology.

Outer cyclone

First, dust is drawn into a powerful cyclone. Centrifugal forces of 500G fling larger dirt, debris, fibres and pet hairs into the clear bin.

Shroud

The air passes through here, while fibres and pet hairs that have escaped the outer cyclone are separated out and directed back into the bin.

Intermediary cyclone

This extra cyclonic stage captures more microscopic dust from the airflow. Any remaining microscopic particles carry on to the inner cyclones.

Inner cyclones

Finally, a cluster of smaller, faster cyclones generate centrifugal forces of up to 150,000G – extracting particles as small as mould and bacteria.
