My upgraded XV-11 just finished a full run that included a normal (as for v2.6) mid-task recharge. All went well - didn't really get stuck on anything at all in 8 rooms and a hallway despite many traps - a very thick mat with tassels, chrome chair legs and a fireplace hearth it can sometimes climb onto.
However, on its return to base, it managed to nudge into, rather than over, the cat-frayed corner of a door mat - a carpet off-cut. It kept shoving the corner further into the mat itself, building an increasingly high loop of carpet ahead, until the whole thing flicked back and over the Neato, covering it completely.
Then as it tried reversing out, the cat climbed on top of the whole arrangement - the mat and the Neato, which was still humming away underneath! Amazingly, despite the turret completely covered, it reversed out, pulling the mat and the cat off, and then continued back to base. Wish I'd had my camera handy.
Maybe this is an undocumented feature of the new firmware? A cat dumper
