Richtech DUST-E MX
Richtech Robotics · USA · 2022
A 270 kg ride-on-sized scrubber that cleans an area the size of nine football pitches, run by nobody.
DUST-E MX is the industrial machine in Richtech Robotics' cleaning line, and the physical opposite of its small sibling: 44 by 22 by 45 inches, over 600 lb (270 kg), cleaning up to 21,958 square feet an hour and rated for spaces up to 500,000 square feet - roughly nine football pitches. Clean and waste tanks hold 17 and 13 gallons. Sensing is heavier than on the compact model: LiDAR, a 3D camera, ultrasonic sensors and an electric bumper that stops the machine on contact. That last item is not a detail. A 270-kilogram autonomous scrubber sharing a floor with people needs a physical layer of protection under the software, and the bumper is it. The machine belongs to the older part of Richtech's portfolio - it predates the line's consolidation into two models - but the fiscal 2025 annual report still lists it as current. Company documents give conflicting tank figures across editions, so the values here follow the product card. No price has been published.
