The 18H26 hot-water pressure washer from Water Cannon is powered by a Honda GX 390 engine, with choice of pumps from General Pump or Cat Pumps. It sits on a portable four-wheel push bar frame for support and ease of use. It provides 4 gpm, 4,200 psi and a 118-degree temperature rise. The triplex ceramic plunger pump is designed to hold 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.
