Stewart-Amos Sweeper

What Stewart-Amos Sweeper does

Stewart-Amos Sweeper Co. is a Harrisburg, Pennsylvania-based manufacturer of street sweeper trucks serving municipalities, commercial contractors, industrial facilities, and airports across the United States. Formed in 2004 as a dedicated subsidiary of Stewart-Amos Equipment Co. (founded 1938), the company operates on an "effectively simple" design philosophy emphasizing rugged, off-the-shelf components that are inexpensive to service and repair. It sells nine sweeper models across two technology lines: the Starfire mechanical broom line (six models, 4–6 yd3) featuring an exclusive 3-shaft elevator system, and the Galaxy regenerative air line (three models, 4.65–6.12 yd3) featuring blast-orifice sweeping hoods and non-CDL chassis options.

The company generates revenue primarily through hardware sales of sweeper trucks, distributed via a multi-state independent dealer network, direct factory sales, and government procurement channels including GSA and HGACBuy contracts. Key value propositions include the proprietary 3-shaft elevator, bolt-together stainless steel hoppers with a 5-year no-rust warranty, and 95% same-day parts shipping. Customer concentration is low and spread across small municipalities, independent contractors, and industrial buyers, with named references such as the Town of Bartlett TN, Armstrong Sweeping, and Clean-A-Lot. The company is privately held, has 11–50 employees, and shows no external institutional funding or AI/ML capability development in the source material.

Core offering

Stewart-Amos Sweeper Co. designs, manufactures, and sells street sweeper trucks for municipal and commercial applications across two product lines: the Starfire mechanical broom line and the Galaxy regenerative air line, totaling nine models with hopper capacities of 4 to 6.12 cubic yards. The company also sells replacement parts (with 95% same-day shipment before 1 PM EST) and provides service support through factory-direct channels and a multi-state independent dealer network.

Product overview

Stewart-Amos Sweeper Co. manufactures two distinct lines of street sweeper trucks: the Starfire mechanical broom line and the Galaxy regenerative air line. The Starfire line comprises six mechanical broom models (S-4c, S-4XL, S-4XXL, S-5s, S-5t, S-6s, S-6t) with hopper capacities ranging from 4 to 6 yd3, using rotating cylindrical brooms to sweep debris onto a conveyor belt into the hopper. The Galaxy line includes three regenerative air models (R-4, R-6, R-6XL) with hopper capacities from 4.65 to 6.12 yd3, using blast orifice technology to dislodge fine particles with air bursts and vacuum them into the hopper. Both lines share a high percentage of parts compatibility, feature stainless steel components, and include options for CDL and non-CDL chassis configurations.
