Good road sweepers are special vehicles and adaptive devices have not matched their performance so far. E 800 and E 1200 prove the opposite: the supposed disadvantage of a not fully integrated, but laterally running suction hose turns into a real and essential advantage. Optimum accessibility resulting from its position allows for its use as a high-performance manual suction device at the same time. The front, consisting of a broom and an aerodynamically optimized suction nozzle, is designed in a consequently asymmetric way as dirt mostly lies at the right roadside. The simple and intuitive control unit is integrated into the existing vehicle joystick.
