Just over two years ago, PerceptIn announced an $8 million Series A. The funding followed a $2 million seed round, and found the startup essentially coming out of stealth to showcase the sensors it was building for a wide range of form factors, from cars to robot vacuums.

The company’s been quite busy in the meantime. In fact, it even went so as changing its name. PerceptIn is now “Trifo” — a punchier name, if not quite as memorable. The company’s currently on its third robotic vacuum, announced today and set to be officially unveiled at CES in a few days.
