A self-contained instant boiler: on its own it heats running water; with a pump unit on top (not included) it becomes a professional hot water pressure washer.

FOX Hot Box
Cold-water pressure washer not included
A self-contained instant boiler, and whatever you mount on top.
FOX packs professional-grade hydraulic, electrical and mechanical components into a solid, compact machine. Its wide flat top takes a high-pressure motor-pump unit (not included), which lets it work as a professional hot water pressure washer.
