Mine is named... whatever my 4yo daughter insists on calling it this month.

I was completely surprised to see the robot vacuum get more affection from my kids than all their toys, and even our cat.

Mine was renamed "bobot", because my 2 year old struggled with the word "robot".

Years ago, my daughter named our Roomba "Puck" because it looks like a giant hockey puck. I liked the double-meaning of it also being the name of the European trickster-fairy (aka "Robin Goodfellow") and so have stuck with it.
