Hotsy BX series

The BX series of gasoline-powered, belt-driven cold-water pressure washers has four models, all powered by Honda GX engines. Horsepower ranges from 5.5 to 13, and cleaning power ranges from 2,000 to 3,500 psi. Two models have a tri-plunger pump with seven-year warranty. The company says the rugged belt-drive configuration, which absorbs vibration and uses a pulley to reduce the pump speed, offers a smooth operation and longevity to the pump.
