Andrew Ashur stands out in a crowd of robotists, and not just because he’s the only one with window cleaner’s calluses under his nails. While the industry is obsessed with humanoid robots swinging their limbs in polished demos, Ashur’s company—Lucid Bots—marches to a different beat. There are no flashy showcases, no robots doing acrobatics in spotless labs. Instead, his machines spend their days out in the real world, clinging to high glass and battered concrete, making a tough, overlooked job less perilous and a good bit smarter.
Lucid Bots operates from Charlotte, North Carolina, far from the West Coast’s relentless swirl of hype, and perhaps that’s for the best. The company builds and sells specialized drones, their Sherpa line, and the Lavo robot, directly to cleaning companies. These aren’t prototypes—they’re workhorses. The engineering, the manufacturing, and the sweat all stay on U.S. soil. Ashur just sealed a $20 million Series B funding round, bringing the company’s total raise to $34 million, and funneling the cash straight back into hiring. Demand isn’t the problem these days. In fact, he laughs: “We’re out of parking. There are more demo requests than hours in my week.” For a founder, he admits, it’s an exhilarating crunch. “When you can’t show off your own robots enough, you know things are moving.”
But it wasn’t always like this. In the early days, nobody was lining up to buy, let alone invest. The team spent five gritty years getting the first hundred robots into the world. Convincing venture capitalists was no breeze, either. Ashur, after all, didn’t come from robotics, but from a patchwork of economics and Spanish classes at Davidson College. The idea first struck him almost by accident. He walked past a building one blustery afternoon and glanced up; a team of window washers was dangling from a swing stage that shuddered like a leaf in the wind. He watched in a chill, imagining how technology might save these workers from the old, unforgiving choreography of rope and risk.
Reflecting later, Ashur explains, “Civil infrastructure is the biggest asset class on the planet. Yet, it’s crumbling. Buildings age, new ones just get taller and more complex, and fewer people want these dangerous jobs. Something had to fill the gap.” That realization sparked Lucid Bots. The company launched in 2018, and to truly understand what cleaners needed, Ashur’s team actually took on cleaning jobs themselves. It wasn’t pretty—two years of scoured hands and chemical burns—but it left them sure how to build machines that would actually help, not just impress on paper.
Now business is picking up pace. The first 100 robots took half a decade. The march toward 1,000 units is going much faster. With every new robot, lessons return from the field. Data streams home from every job, feeding the company’s software. Each update ripples out across their product line, sanding off rough edges, sharpening performance. And Lucid isn’t stopping at windows: they’re adapting their technology for tasks like painting, waterproofing, even sealing. The core robot stays the same, retooled for new jobs, driven by the demands of customers who keep tugging Lucid into new territory.
Ashur beams as he recounts a recent milestone: “We waterproofed a whole university stadium—a beast of a job—using essentially the same platform as our Sherpa. Demand just pulled us in. We were getting fifty inbound leads a month for painting and coating, and that was before we even started marketing it.”
The story of Lucid Bots isn’t built on spectacle—it’s written in sweat, trial, and error. In an industry hungry for glossy demos and big promises, Ashur and his team have built something a lot less glamorous, but far more remarkable: robots that disappear into the real world, taking on the grunt work, and making tough jobs safer, one pane of glass at a time.
