Dyson's testing philosophy: break it until it fails, then rebuild it better.

Here's what that actually means in practice: vacuum batteries go through 1,200 charge/discharge cycles, the Supersonic hair dryer cable gets wrapped and unwrapped 7,800 times, Corrale straightener plates open and close 400,000 times, and purifiers run 24/7 until they fail.

By testing to failure, Dyson discovers the exact limits of materials, mechanisms, and electronics before the product ever reaches a customer.

Dyson tests until things break, studies why they broke, then redesigns around those failure modes.

It's the same principle behind Tesla's rapid iteration on Starship (blow them up until you understand what fails).

The difference between "it works" and "it lasts" is understanding failure modes.

This is what separates consumer products that last 2 years from ones that last 10. The engineering discipline to destroy your own work, learn from it, and build the next version smarter.

P.S. Would love to see more robotics companies adopt this level of durability testing. Most demos show success. Few show the 400,000 cycles of wear that prove it actually works.
