I call mine Cletus, because it ain't the smartest tool in the shed. At least once every run I have to kick it out from under it's nemesis...my living room chair. Where it has been bumping into the legs for 20m.
Our random mapping one was such a frustrating piece of garbage it was just thrown into the closet after a few weeks. My Wyze lidar one is amazing - you can even just yank it off the floor, set it somewhere else, and when you resume it’ll go right back to where it left off and continue.
I know it uploads the generated map to the cloud, but I don’t really care because it keeps my upstairs clean without me lifting a finger.
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.
The one that behaves really poorly has been through a series of names from "Ceiling" (because I thought it'd be funny to see a notification telling me that Ceiling is stuck and ended its job), to Hessalam ("Last Chance" from wheel of time) and is currently named "Chaos Monkey". I hate that damn thing.
