This beast's Briggs & Stratton engine combines with a triple pump to crank out a professional-grade 3,300 psi. Paint on brick and stain on the deck had no place to hide. It even removed a layer of stain hiding under the topcoat. A keyed electronic start is a nice feature, but even if the battery is dead, it's nice to know it only takes one or two pulls to start manually. [$800;]
