Lucid Bots raises $20M to keep up with demand for its window-washing drones 

Andrew Ashur, the founder and CEO of window cleaning robot startup Lucid Bots, likes to joke that his company is the antithesis of the robotics industry right now.

While many companies are trying to build humanoids or tout demos of their robots dancing and doing flips, Lucid Bots’ drones are out in the field making traditionally unsexy and dangerous work, like cleaning windows, safer and more efficient.
