Well, you are unlikely to be the *only* one who doesn't think this is all that impressive, because you're unlikely to be the only one who didn't read the article or looking up the device on the company's website.
The robot in question is designed to capture energy from surface waves for propulsion. So it is not a deep submersible, it waddles along a six meters below the surface, tethered to a streamlined surface buoy that it drags along and uses to capture wave energy. Making it through a major storm is a significant proof-of-concept for such a system.
