Newark, Calif. -- Neato Robotics, a Newark-based developer of robots designed to perform household chores as intelligently and efficiently as humans, on Thursday raised $12.2 million in its fourth round of funding, co-led by Vorwerk Ventures and Noventi Ventures. The company plans to use the proceeds to expand operations, sales and marketing, as well as to bolster product development. "Our vision is to leverage our unique robotic technology to bring new, innovative home-cleaning products to the marketplace," said CEO Warren Flick. Founded in 2004, after its first product concept won a Stanford University Graduate School of Business competition, the company has since raised $35 million in funding. The company's core technology features an intelligent, laser-guided navigation system, paired with a robotic vacuum cleaner system.
