Mi-T-M HS-3506-1MGK Hot Water Pressure Washer – 3500 PSI, 5.6 GPM

The Mi-T-M HS-3506-1MGK delivers 3500 PSI at 5.6 GPM — the highest flow rate in the HS-3506 series — powered by a 725cc Kohler CH730 OHV engine and a General pump. The burner produces 471,800 BTU/hr with a 150°F temperature rise to 200°F max outlet. It includes a 2900W generator, electric start with sealed battery, dual cogged belt drive, and ½-inch Schedule 80 stainless-wrapped coil. Weight is 760 lbs at 50" × 34" × 46".

High Flow Rate and Heat Output

  • Pressure: 3500 PSI at 5.6 GPM — 5.6 GPM is the highest flow rate in this HS Series group; faster large-area rinse and soil removal than lower-GPM models.
  • Engine: 725cc Kohler CH730 OHV — large-displacement commercial engine with electric start and sealed battery; 10.0-gallon engine fuel tank.
  • Heat: 471,800 BTU/hr, 200°F max — 150°F rise above ambient; 10.0-gallon burner tank at 3.37 gph fuel consumption.
  • Pump: General — external bypass, preset unloader, forged brass manifold, stainless-steel inlet strainer.
  • Generator: 2900W — onboard power for remote site operation.
  • Weight: 760 lbs — trailer mounting recommended at this weight.

Applications

The 5.6 GPM flow rate makes the HS-3506-1MGK the most efficient HS Series model for large surface area cleaning — wide concrete aprons, ship decks, aircraft hangars, and expansive equipment yards where throughput per hour matters more than maximum pressure. The 471,800 BTU/hr burner supports sustained high-temperature output at the full 5.6 GPM flow. Included accessories: quick-connect nozzles (0°, 15°, 25°, 40°), 50-ft hose, dual lance. Optional add-ons (at order): adjustable thermostat, hour meter, dual gun kit, four-point lift, detergent valve.
