Dyson: There wasn’t any, to be honest. When I first introduced the bagless vacuum, I was laughed off by every vacuum and appliance company you could think of. Even when they were satisfied that the technology worked, they were more interested in defending the market for vacuum cleaner bags, which made more money than the vacuums themselves – the razorblade business model. It took one Japanese company to take a chance on me to prove to the industry this was an idea worth investing in.
