" It was Tomy, of all companies, that released what was technically the first robot vacuum back
in 1985. Sure, the Dustbot was a big-eyed, extremely blinky kids' toy, but the dustpan and
brush it carried was nought but a clever ruse. There was a vacuum in there, and it was able
to sense edges and change directions. Not the most efficient thing in the world, not even
particularly useful really. But it was the first.
