Headcannon that when Alfred finally caves and allows the Wayne family to get a roomba, the bat brothers just go nuts over it:
Damian names it, and gets disgruntled when people simply refer to it as “the roomba”. Like, no, that is Cerberus? Get it right please
Tim tampers with it on more then one occasion. Hooks up some motion activated speaker/microphone mechanism complete with a voice modulator so that he can speak to whoever it passes. Steph is convinced for a whole WEEK that the roomba is sentient
Jason puts a few knives sticking out from it at some point. The whole family can hear Bruce’s screams when it enters his study.
And Dick just turns the damn thing off every time he sees it. He thinks it’s the worst purchase of all their collective lives
