Built for long, demanding commercial jobs, this Alcota hot water trailer-mounted pressure washer stands out with its impressive 460-gallon water tank, delivering extended runtime and fewer refill interruptions on large sites.

Despite the massive capacity, the unit is engineered around Alcota’s Hot Water Narrow Frame design, offering one of the narrowest frames on the market for smarter trailer space utilization and easier maneuvering in tight work areas.

Mounted on a tandem axle trailer for superior stability and load control, the system is powered by a dependable 18HP Honda GX690 engine, producing a high-output 8 GPM at 3,500 PSI for fast, aggressive cleaning.

Featuring Alcota’s hydro-insulated Schedule 80 heating coil, diesel-fired burner, and heavy-duty triplex pump, this commercial unit delivers exceptional heat efficiency, safety, and durability—making it an ideal solution for contractors and industrial operations that demand maximum water capacity without sacrificing space efficiency or performance.
