Digital motor V9
125,000 RPM. 13 stator blades milled to ±0.001mm.
V9 DIGITAL · CORDLESS SYSTEM
A 4.3 oz motor spinning eleven times faster than a Formula 1 engine, balanced to 0.0001 g so it can idle in your hand without a shudder. Built in Kellings Cross, tested for 14,600 hours before it shipped.
Four components, one airpath. No hoses, no bags, nothing to replace but the filter — once a year.
125,000 RPM. 13 stator blades milled to ±0.001mm.
79,000g of centrifugal force flings particles from the airflow before they ever reach the filter.
Captures particles down to 0.1 microns. Rated for 2,600 liters of air per minute.
Nickel-cobalt-aluminum chemistry. 60 minutes on Eco, 6 on Boost.
Tested at the Kellings Cross Acoustic & Particulate Lab, batch QA-2291, ISO 3744 chamber.

The aluminum tube carries current to the brush head at 22 volts, so it has to be rigid enough not to flex under torque and thin enough to stay under 640 grams. We tried nine wall thicknesses. This one survived an 80,000-cycle fatigue rig.
