SHANGHAI/TOKYO -- Robot vacuum companies from China are cleaning up globally with cutting-edge features and affordable prices, as shown by the player behind Ecovacs cleaners surpassing the maker of Roombas in sales last year.
The Chinese business, formally known as Ecovacs Robotics, is hoovering up more than consumers. Investors are embracing the company's growth potential, sending its market capitalization near 44 billion yuan ($6.38 billion) -- roughly five times that of U.S.-based iRobot, the Roomba manufacturer.
