章 57: The Prototype Was A Great Success

On the 10th of January 20X9, in the research and development plant of Xing Hai Technologies located inside Bao Shan Industrial Park, after a grueling development schedule of 45 days, the prototype of the "Wa-Wah: first generation" cleaning robots had been successfully created!

The speed of the development process was out of this world! Usually, it took about three months to develop this type of robot. But the team, including Su You Jie and Zhou Kun, only took half of that time.
