What impresses me about these ads is that they speak directly to the consumer, they irritate a problem and then offer a solution.  In this ad, the inventor is going on about how inconvinient it is to have a vacuum cleaner that can’t turn around corners.  He spends a great deal of time talking about this issue.  He explains the problem in depth and then offers his solution.  By the time he is done talking, you are thinking “well of course, why didn’t anyone else think of that before”.  His solution is so simple that it is the only obvious choice.

He has run great ads before and they all seem to follow the same format.  Speak directly to the consumer, irritate the problem and then offer a simple solution.  Simple wisdom that any marketer can use.
Great job, Dyson.
