The idea was inspired by my own daily life. Living with flatmates, I usually cannot use the vacuum cleaner on weekdays because of the noise. With OMIT, life can be less noisy and handier by omitting electricity. It can be also used at any time of the day and in any place. It was very important that the mechanism has to be able to accumulate power. The idea of the combination of planetary gears and torque springs is taken from a car toy, which works with small torque springs. Furthermore, I found out that before the appearance of electric vacuum cleaners, manual vacuum cleaners were used in the 19th century. So I thought vacuum cleaners can be less noisy and more handy by omitting electricity.
