House Sweeper Concept

Since my childhood I did the vacuum cleaning at home. I saw so many design flaws on the vacuum cleaners I used. Especially the current trend of cyclone battery powered cleaners with handle heavy designs are completely on the wrong path.

I created my design based on the real-world use cases instead of creating an over engineered fragile and expensive house hold gadget. The main objective of my design is to remove the dust, dirt and hair from the floor and the carpets. All critical parts of the design are contained in the cleaner head section. The handle is just a bar to navigate the cleaner. Even the on/off switch is placed on the cleaning head.

The design is simple. A drum that is covered by high strength nylon velvet to remove dust, dirt and hair from the surface. Nylon is a very durable material and is very positively charged when rubbed on the surface. The drum would have a rubber section on its center to grip the surface better. The drum is connected to the cleaning head using ball bearings for low friction and longevity. The movement of the drum is controlled by the user itself and not by a motor. After the drum picks the unwanted particles from the surface, it would release them when it gets into contact with a PTFE comb. PTFE would be negatively charged which would mechanically and electrostatically remove the particles from the drum surface. The brushless dc centrifugal pc fan would blow these particles toward the dust collector tray. The curved and of this tray would have a filter which lets very fine particles to get through. Due to curvature and the covered top, these particles would immediately settle on the floor. This setup negates the HEPA filters which reduce the efficiency of a vacuum cleaner considerably. A typical battery powered vacuum cleaners raises the fine dust particles from the ground and accelerates them up in the air. If there were no HEPA filter, then the flying up dust would be hazardous to our lungs. However, a fine dust on the floor has no risk for our lungs. In real world case, capturing such dust if you can release them on the floor without steering the air is waste. By the second you open a window, way more dust would fill up the room. Don’t forget that the cleaning is done for a home and not for a semiconductor manufacturing plant.

My house sweeper would be powered by a tablet battery to maintain its low profile. Direct path of air flow and less dense air filters allow good cleaning with small motors and batteries. There is no loss of efficiency due to raising the dust at least a meter from ground and then accelerating in a cyclone setup to separate it. Much more importantly handle heavy designs are susceptible to breakage. Heavy motor and battery structure creates a very high center of gravity. Moment the handle slips from the hands, all the expensive part of a vacuum cleaner is cracked and very expensive servicing would be required. That’s why people are hesitant on handing these gadgets to house cleaners who handle them carelessly.

My design costs way less than the traditional battery powered vacuum cleaners and would experience no breakage problem. Can be safely handed to a careless house cleaner.
