Dyson re-designs litterally every part in any contraption they manufacture.
But they make as a habit ONE big mistake. Dysons 1st law boils down to: function follows form.
They make beautiful mediocre things with a price-tag that make insecure punters think they bought the best.
Funny, because it comes usually with a cash-back option that is large enough to buy a really good machine.
My personal opinion is that they have more marketeers and lawyers on their payroll than SF in its heydays.
And of course they advocate the rules that suits them best. And to go to the courts that suits them best.
Brexiteer Dyson was disputing the EU’s own energy efficiency labelling for vacuums, which allowed testing to be done with empty new machines. Dyson claimed this discriminated against its bagless machines in favour of continental rivals which used bags and filters, because bags and filters clog up with dust over time, reducing efficiency. Dyson argued this ignored the EU’s own directive, which says efficiency must be calculated to “reflect normal conditions of use”. So he appealed to the European Court of Justice. The ECJ sent the case back to the lower court after finding it had “distorted the facts” in the original ruling. Dyson won this 5yr battle.
