The 18H26 hot-water pressure washer from Water Cannon is powered by a Honda GX 390 Engine, with the choice of a General Pump or Cat Pump. It sits on a portable four-wheeled push bar frame for support and ease of use. It provides 4 gpm and 4,200 psi and a 118-degree temperature rise, and includes an upgraded external recirculation-plumbing feature that cools the water while the trigger gun is closed. The triplex ceramic plunger pump holds up to commercial and professional daily use. It comes with an overheat safety valve that opens and closes automatically to allow the recirculating higher-temperature water to be released and allow cool water to replace it, helping to protect the wear parts. 800/333-9274; www.watercannon.com.
