LG has refreshed the 5th generation of Roboking vacuum cleaner robots. Most of the technology and design remain the same, but thanks to some fine tuning the robot does better job than the original fith generation announced late 2009. The previous Roboking had a noise level of 50 dB what made it the most quiet vacuum cleaning robot on the market. LG managed to get it even better by going down to 48 dB, keeping the title ahead of the improving competitors. But the Roboking VR6170LVM is not only quieter, it moves 30% faster, thanks to some algorithm optimizations.
