Gizmodo’s got a roundup of the best robotic floor cleaners…check it out!

It seems impossible, but we live in age when robots can clean our floors for us. You don’t have to be Donald Trump or Emperor of Mars—this is science fact. But which floor-bot is dominant? We have answers.

A robot cleaner has to suck up the dirt, obviously—and most importantly. But it also needs to be smart. It needs to navigate around the shoes you’ve strewn about, your couch, and not fall down stairs. It needs to be able to find its way back home without knocking things over. It needs to not get stuck. It needs to be precise enough to get into those deep, grimy edges under your kitchen counter.

We brought together the current triumvirate of sanitation automatons. Only one will rule supreme—the other two will be shot with a disintegrator beam, their ashes cleaned up by the champion as one final act of domination. Let’s begin.
