Dyson just solved the tipsy canister vac problem. The Dyson Cinetic Big Ball vacuum automatically rights itself if it falls over.

Inventor James Dyson, the company’s famously persistent owner, challenged some of his 3,000 engineers to solve the biggest problem with canister vacuums. According to the company, 55 engineers built more than 1,000 prototypes that traveled more than 10 miles picking up 3,900 pounds of test dust in the Cinetic Big Ball development phase.

“The problem with some canister vacuums is that they can go off on a tangent and topple, leaving you to walk back over the floor you’ve just cleaned to right the machine,” Dyson said. “We challenged our engineers to refine the canister format, to solve this problem and others. The Dyson Cinetic Big Ball canister is the only vacuum that self-rights when toppled.”

The Dyson engineers finally solved the problem by designing a spherical body, with its heaviest components on the bottom. Because the ball has a low center of gravity, whenever it leans or topples sideways, gravity pulls it upright.

Inside the sphere, the air moves pretty fast. According to company specs, air moves at more than 100 mph when it enters the vacuum’s cyclone pack. In the cyclone pack the air accelerates to 180mph, generating more than 100,000 G-force to pull out microscopic particles from the airflow.

When the debris bin gets full, a “hygenic dirt ejector” assembly uses a silicone collar to scrape off dirt and dust so that everything goes out, leaving the bin empty. No more sticking your hand in to pull out clumps or tangles.

The Dyson Cinetic Big Ball comes complete with tools including a carbon fiber turbine floor tool for all types of flooring. You won’t have to buy bags or filters due to the design dirt capture and ejection design.

The $600 Dyson Cinetic Big Ball is available on the company website September 1 and will be at major retailers by September 16, 2016.
