It seems that the VR6260 has standard spray coating whereas the VR6270 has UV spray coating with 3D effect.

Auto Turbo Feature
Both of the LG VR6260 and VR6270 have the Turbo Mode. In the Turbo mode, the Robot speeds up the RPM for brush and suction motors to run more powerfully and better the cleaning result.
The LG VR6270 also features an auto turbo function that enables the Robot to detect carpet and automatically set to turbo mode to clean carpet.
