Through product analysis James Dyson found a problem with old vacuum cleaners whose design had remained the same since the early 1900’s. He became frustrated with his vacuum cleaners diminishing performance: dust kept clogging the dust bag, reducing suction. Dyson had the idea of using cyclonic separation to create a vacuum cleaner that would not lose suction as it picked up dirt. The cyclone idea came from the spray-finishing room's air filter in his Ballbarrow factory.

Dyson’s first original invention, the Ballbarrow, was a modified version of a wheelbarrow using a ball instead of a wheel. This was featured on the BBC's Tomorrow's World television programme.

Dyson continued product analysis on his own design and found a further problem. It was difficult to turn the cleaner because of its fixed wheels.

Design and technology should be the subject where mathematical brainboxes and science whizzkids turn their bright ideas into useful products
