> Earliest Roombas navigated by touch (bumping into walls)

My ex got a Roomba in the early 2010s and it gave me an irrational but everlasting disdain for the company.

They kept mentioning their "proprietary algorithm" like it was some amazing futuristic thing but watching that thing just bump into something and turn, bump into something else and turn, bump into something again and turn again, etc ... it made me hate that thing.

Now when my dog can't find her ball and starts senselessly roaming in all the wrong directions in a panic, I call it Roomba mode.
