Dyson Big Ball™ vacuum - Technology

Picks up microscopic dust. And itself.

Self-righting Dyson Big Ball™ vacuum
Self-righting Dyson Big Ball™ vacuum

Self-righting technology.

Dyson Big Ball™ vacuums are monostatic – they have a single, stable resting point. By assembling the vacuum’s components in a spherical array, with the heaviest near the floor, our engineers created a curved body with a low centre of gravity. It’s naturally stable, but if it gets knocked over, gravitational force automatically self rights it. And its spherical shape means it turns easily on a point, so it's highly manoeuvrable.

2 Tier Radial™ cyclone technology.

19 compact cyclones arranged over two tiers generate powerful centrifugal forces, to capture microscopic dust and dirt particles. The radial formation channels airflow through the centre of the cyclone assembly to maximize suction.

Bin emptying mechanism
Bin emptying mechanism

Hygienic bin emptying system.

The stainless steel shroud is chemically etched with 19,000 holes, each measuring 450 microns x 450 microns. This creates a smooth surface for the silicon shroud-wiping collar to slide down, driving out trapped dust and debris.

Carbon fibre turbine cleaner head.

The air-powered cleaner head’s 1,644,000 carbon fibre filaments dissipate static charge to remove fine dust from hard floors. And 6,124 stiff nylon bristles drive deep into carpet to remove ground-in dirt.


  • mm control on the center of gravity, so the vacuum always rights itself


  • Air Watts of suction power


  • Compact cyclones tolerance during chemical etching of the bin shroud
