It’s also pretty much exactly what it sounds like. The Brick Wall created a Mad Max-esque robovac made almost entirely out of Legos that sweeps up and collects bricks left lying around the house. The ingenious contraption can gather pieces of almost any size and even has a retractable robotic arm. The major difference between the Lego Roomba and real robot vacuum is that it’s not autonomous. Instead, it’s controlled by a manual remote. Still, that’s a hell of a lot easier than picking all those bricks one at a time. And given how fun the Lego Roomba looks, parents may even be able to convince their kids to clean up after themselves.
