So you're saying roombas are more efficient than my adhd brain..

I'm not mad at it.

The model we have (that’s only a few years old) works like this. My favorite is when it’s trying to get back to the dock, it’ll just move aimlessly until it accidentally reaches the vicinity of it and can make it home. A lot of times it runs out of battery. Or gets stuck somewhere (in the same spots because I can’t tell it to avoid problem areas).

Brand name ones still work like this pretty much, they're pretty bad
