Laser detects the particles you can't normally see - so you don't miss anything.32

Makes the invisible visible

A precisely-angled laser makes invisible dust visible on hard floors.32

Green laser

The human eye's evolutionary sensitivity to green light means we see it brighter than other colours, enhancing contrast and making hidden dust clearly visible.


A piezo sensor continuously sizes and counts dust particles.34

Measures microscopic dust particles

The piezo sensor measures dust particles passing through the inlet 15,000 times a second.

The sensor converts the acoustic vibrations of picked-up particles into an electrical signal, allowing the vacuum to intelligently react when more dust is identified.34


Suction power automatically adapts to dust levels.34

Powerful Dyson suction when you need it

A powerful Dyson Hyperdymium™ motor increases suction power when higher dust volumes are identified.34

Scientific proof of a deep clean

Our latest technology calculates and categorises sucked-up particles - showing you what's being removed as you clean.34

Particles the size of allergens and pollen

Pollen is commonly carried into homes on skin, hair, clothes, footwear and pets. Once inside, pollen grains and antigens accumulate in house dust, reaching a peak concentration long after pollination season.

With their microscopic size and jagged shape, pet allergens can easily stick to upholstered furniture, bedding and fabrics – and often stay in the home for months as house dust, even after the pet is gone.

Particles the size of microscopic dust and skin flakes

Moulds measure up to 100µm and can be found around kitchens, windows, and other damp areas. Their spores can irritate the nose and throat, causing shortness of breath.

Particles the size of dust mites and fine sand

House dust mites are one of the major indoor triggers for allergies and asthma. Each mite produces about 20 droppings a day, which continue to cause symptoms even after the mite has died.

Particles the size of sugar and fleas

These larger, visible particles are trapped in the bin as soon as they enter the primary cyclone and metal mesh filter – clearing the airflow, so there's no loss of suction.32

Whole-machine advanced filtration
Expels cleaner air into your home.
Dyson's fully-sealed system traps dust and seals in 99.99% of microscopic particles as small as 0.3 microns (µm).38

1. Bin cyclone

Primary separation removes the largest particles. Powerful centrifugal forces separate dust, dirt and hair from the airflow.

2. Metal mesh filter

The stainless steel filter has 7,298 square holes, each created using chemical etching. They filter out anything over 400 microns.

3. Powerful cyclones

11 root cyclones generate forces of up to 100,000g to remove dust from the airflow - so there's no loss of suction.39

4. Pre-motor filter

Electrostatically charged Technostat® layer attracts smaller particles that would otherwise pass through.

5. Post-motor filter

1.6m of PTFE folded 112 times traps 99.99% of particles down to 0.3 microns, so you don’t breathe them in.38
