บท 58: Original Equipment Manufacturing (OEM) Factory

On the 17th of January, after another week of modifications, improvements and upgrades, the "Wa-wah: First Generation" cleaning robot was successfully finalized!

Its basic functions and parameters were as follows: The product dimensions were a length of 345mm, a width 345mm, and a height 506mm; weight was estimated at 5.8kg; the battery was a 15V/ 10200 mAh lithium battery; the power rating was 65W (sweeping) / 75W (mopping); the working duration was 160 to 180 minutes (sufficient to finish cleaning a 200 square meter house); and the cleaning index was 99.6% to 99.8%

That's right, Chen Jin had set a target of 99.9% for the crucial cleaning index, in order for him to claim that it could get rid of 99.9% of all rubbish and dirt. But, due to the layout of a room, its various installations and the material of the flooring, it was difficult to reach such a target. It could only be achieved in the most ideal working environment.
