The Blastman B20S Generation 4.0 is an advanced industrial blast cleaning robot designed for high-precision surface preparation. Featuring eight programmable axes, including telescopic and joint booms, it efficiently reaches complex geometries and enclosed areas such as railcar interiors. Operating on roof-mounted rails, it handles nozzle diameters between 13–19 mm at pressures from 4–11 bar. The robot offers a cleaning rate up to 200 m²/h and ensures durability with IP65 sealing for harsh environments. Ideal for railway, steel, and foundry applications, the B20S minimizes manual labor, enhances safety, and delivers uniform cleaning results through automated, programmable operation.
