Yuya doesn't know what the exact robot was, but the description brings to mind similar vacuums from home.

He covers his mouth with the back of his hand as he sucks in a sharp breath against, honestly, how hilarious is it to imagine usual flaming Strange running around trying to escape a tiny roomba. Normally he'd probably find someone laughing at his efforts offensive, which is the biggest reason Yuya is trying not to be obvious.

But he's still kind of obvious. "Is--is that how you got caught?"
