Components of the Dyson Cinetic Big Ball are assembled in a spherical array, with the heaviest nearest to the floor. Whenever the vacuum is displaced, gravitational forces will automatically return it to its upright resting position.
It’s also the only vacuum with no maintenance and no loss of suction, as there are no filters to wash or replace and no bags to buy (or so the company reckons).
British entrepreneur and inventor Sir James Dyson, said: “The problem with some cylinder 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."
"We challenged our engineers to refine the cylinder format, to solve this problem and others. The Dyson Cinetic Big BallTM cylinder is the only vacuum that self-rights when toppled. Further advances include hygienic dirt ejection and an articulated handle.”
Dyson was previously embroiled in a heated hoover battle with rival vacuum maker Bosch, which it accused of cheating "like VW" in energy efficiency tests.
Dyson had challenged what it said were the more misleading aspects of the energy label regulations in a judicial review by the European Courts.
It came to an abrupt end when the European Court of Justice (ECJ) dismissed the legal action, saying current energy label tests do “not infringe the principle of equal treatment”.
