Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.
