OMIT is obviously not comparable in terms of power to a traditional vacuum cleaner, but it is silent and useful. I wish I could say the same thing about everyone I know. Ah! I almost forgot. It does not require electricity: an object that brings a bit of comfort even off-grid.
The designer thought of OMIT while living with roommates because he couldn't use the noisy vacuum cleaner on weekdays. “I realized that around 70% of users can only use the vacuum cleaner on weekends, due to noise and cable problems. All things considered, it was a "rediscovery": in the XNUMXth century there were already manual vacuum cleaners. Without electricity they can be quieter” Furthermore, I discovered that before electric vacuum cleaners, manual vacuum cleaners were used in the XNUMXth century. I thought vacuum cleaners could be less noisy and more manageable by omitting electricity,” says designer Hiroyuki Morita.
How OMIT works
This compact vacuum cleaner works by turning the knob several times. The force is transmitted to the suction fan which increases the number of revolutions with a special mechanism. OMIT requires 5 turns of the knob to operate 10 seconds. To achieve sufficient suction power, the mechanism works with several key elements. The first it is the gear that increases the number of revolutions from 1 to 600. To create the necessary force, The second one element is a torsion spring which makes OMIT work longer. The third key element is the needle bearing which rotates only in one direction and constantly transmits the force of the torsion spring to the gear. The collected dust goes into a washable container that is easy to clean and maintain.
OMIT uses the principle of the free wheel in its mechanism where pulling a string causes a wheel to spin constantly. However, the action of pulling the cord is physically difficult to do if you want to maintain the vacuum cleaner's power long enough. The key was understanding how to control the direction of the air.
To make the rotation easier and more stable, I added a torque spring and a planetary gear. The combination translates small actions into a large number of spins. When I found the principle, I designed the optimal arrangement of the components.

The “electric” vacuum cleaner without electricity: a progenitor?
The absence of electricity challenges traditional portable vacuum cleaners. OMIT could be a new type of cleaning products: more powerful than the broom and with fewer resources than the vacuum cleaner. It is minimal but powerful and solves the problem of noise plus that of electricity consumption. OMIT is ideal for cleaning small spaces such as kitchens and desks, as well as car interiors, with the added bonus of energy saving.
