In this undated image released by Sharp Corp. Cocorobo sold by the Japanese electronics maker is shown. It looks just like iRobot's Roomba vacuuming machine, except the new circular roaming vacuum cleaner from Sharp is trilingual, and even knows a hip humorous dialect. Cocorobo, which can also send photos taken from your home to your cell phone, says 36 phrases including "Long time no see" and "Hello," in Japanese, English and Chinese. Cocorobo sells for 130,000 yen ($1,600) and goes on sale next month in Japan, and later in China and other Asian nations.(AP Photo/Sharp Corp.)
