LG has recently launched a floor vacuum robot similar to the iRobot Roomba called Roboking in Korea.
Outside of Korea the LG floorvac robot is dubbed LG V-R4000 (product page).
Korean Popco has published a review of the LG Roboking floorvac with many photos. Out of some reason they published the story text as image, making it impossible to translate automatically. Still worth to visit for the images. The LG V-R4000 measures 340mm x 133mm. The LG robot cleans with 0.3m/sec. Runtime is 70min. The Roboking needs 2.5hours to charge.
No word on where and when the LG floorvac will be available.
