Why ordinary vacuums lose suction

Bagged vacuum cleaners

The bag is meant to trap dust and dirt, and allow air to escape through millions of tiny holes in the paper. But when you start to use a bagged machine, dust and dirt 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 Root Cyclone™ technology don’t

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

 

Root Cyclone™ + core separator

In our latest machines, Dyson engineers have combined Root Cyclone™ technology with a core separator – 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.

Outer cyclone

First, dust is drawn into a powerful cyclone. Centrifugal forces of 500 G 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.

Inner cyclones

Finally, a cluster of smaller, faster cyclones generate centrifugal forces of up to 100,000G, extracting particles as small as mould and bacteria.
