Commercial hardware. 4000 PSI / 3.5 GPM with direct-drive pump and 15 HP gas engine—built to work daily, not “weekend warrior” duty.
Electric start. 12V system simplifies starts when you’re bouncing between sites. (Battery spec: ≥165 CCA.)
Real chemical control. Standard downstream injector; swap to black nozzle for soap draw and adjust flow at the injector.
