How to Pick a Medium Semi-Pro Gas Power Washer

If pressure washing for you is more than a serious hobby but less than a career, then a semi-pro gas pressure washer is the perfect fit for you. These power washers have all the features a professional demands, with a price tag that won't wash your wallet out.

Medium semi-pro pressure washers
are popular with farmers, contractors, and serious weekend warriors. The first step is deciding on the type of pump you need.

Professional Pump Options

Honda GX Power Washer Engine

We named this grade of pressure washers "semi-pro" because they bridge the gap from consumer to professional. Our semi-pro units are designed with many features you'd find on a professional unit.

Nearly all of these washers come with a professional grade
spray gun
something you'll appreciate when taking on big jobs. Some even come with a
pro-grade powerful engine to spin the pump on semi-pro units. The pump is what pressurizes the water. So the better the engine, the better the pressure. Look for units with a Honda GX engine.

Axial Cam vs Triplex Pumps
Axial Cam PumpAxial Cam pumps use direct-drive mechanics and spin at the same speed as the engine, which wears down faster than a triplex pump but can still be replaced (unlike the wobble pumps found on entry-level models.)

Triplex Power Washer Pump

Triplex plunger pumps are more expensive but offer longer life and better performance. If you intend to use your power washer on a
daily basis, it's well worth the expense. This pump can also be rebuilt.

Spray Tips Consumer Spray Tips
A nice feature that accompanies medium semi-pro gas pressure washers is an army of
spray tips - allowing you to tailor your spray to your cleaning task.

If you're rinsing detergent from your siding, go with a wider spray. But if you're blasting mud or concrete from your tractor, choose a concentrated jet spray. In a 5-pack, the tips are:

  • 0° - red, concentrated pencil jet
  • 15° - yellow, high performance
  • 25° - green, multi-purpose
  • 40° - white, sensitive surfaces
  • 65° - black, low-pressure detergent application
