Stewart Amos Starfire S-4c

From chip seal milling operations to heavy city street cleaning, the Stewart Amos Sweeper Co.’s Starfire S-4c can handle it.


The S-4c is a heavy duty, 4.0 yddual engine mechanical broom street sweeper mounted on a highly maneuverable cab over chassis. No CDL is required! It's as productive as sweepers mounted on larger trucks.

Manufactured with reliability and simplicity in mind, the S-4c is built for day-in and day-out continuous duty sweeping. The short wheel base chassis creates an extremely tight turning radius making it perfect for cleaning confined city streets, cul-de-sacs, construction sites, milling jobs, and open highways.
