Another month, another firmware upgrade for Neato robots. Neato Robotics has released another firmware upgrade to its popular XV-11 (XV-12 and XV-15) vacuum cleaning robot. Firmware version 2.6 promises very little, and the changes seem to address the docking procedure and the way the robot stays on the dock while charging. (Interestingly firmware version 2.4 was promising the exact same thing.) The latest upgrade includes all the previous improvements as well, and is compatible with all three variants of the XV series from firmware version 1.0 and up.
