Builders of all ages struggle to keep LEGO pieces off of the floor. But those days may soon be over thanks to The Brick Wall! Rather than buying an autonomous floor cleaner, The Brick Wall brought us an invention that could revolutionize any LEGO fan’s life. It’s called the Lego Rumba.

This fully motorized and untethered device can sweep up small technic pins, medium plates, large bricks—even minifigs—from a flat service into a holding bin. Two sets of treads provide the business end of the creation, with rubber strips stuck into the grommets for sweeping power. A robotic grabbing arm allows the model to pick up extra-large items like Technic tires. Click the video below to see the LEGO Rumba in action.

While not conventionally beautiful, the open sides of the model provide an unobstructed look at the functional components that make this contraption go. Check out more of The Brick Wall’s marvelous creations on YouTube.
