Dyson claims to be revolutionary in the world of vacuum cleaners, but its professional business logo follows all of the rules. This vacuum cleaner is known for its ‘Dyson ball' vacuums, and as such, it is very appropriate that the letters of the logo are so rounded. Round images make people feel that they are part of something, in this case part of a vacuum cleaner company that has completely overhauled the way vacuums are designed and manufactured.
