Stewart Amos Starfire S-4XL

The S-4XL is a heavy duty, full-featured 4.5 yd3 dual engine mechanical broom street sweeper that is mounted on a large conventional chassis that does not require a CDL to operate.

Manufactured with reliability and simplicity in mind, the S-4XL is built for day-in and day-out continuous duty sweeping – from chip seal & millings, to heavy spring clean-up to mile after mile of open highway.

The environmentally conscious S-4XL is SCAQMD PM-10 Rule 1186 Certified.
