Extensive real-world prototype testing and feedback refined the sweeper design to provide customers with exactly what they want and need, while proving the reliability and durability along the way. The input of service technicians, operators, and street sweeping supervisors shaped every detail of the new RegenX^® mid-dump regenerative air street sweeper from Elgin Sweeper Company, a sweeper that is easy to use, easy to clean, and easy to maintain but still delivers the quality and proven technology that is the hallmark of Elgin Sweeper products.
