The second edition of the 5th generation of LG Roboking robotic vacuum cleaners keep the first position for LG as the quietest vacuum cleaner robot on the market. With a noise level of only 48 dB (as opposed to 50 dB in predecessor) the Roboking VR6170LVM moves 30% faster, thanks to some optimizations. It can also detect very thin obstacles (like chair legs) as long as they are at least 1 cm thick. The new robot is equipped with 51 sensors, and is able to continue cleaning in the exact position where it was stopped last time. Just like the previous model, this robot uses a dual camera system to map its position.
Same as LG Roboking VR6171LVM, but red instead of blue. It is a Korea only model.
