Do you look forward to spring so you can get back into your regular weekly pressure cleaning projects?
If pressure washing is a hobby you take seriously, but not a daily means of making a living, a medium semi-pro gas pressure washer is the perfect fit for you.
These power washers have all the features a professional demands, although a pro may opt for something with a little more power.
Medium semi-pro units are popular with farmers, contractors and extreme-DIYers.
Axial Cam vs Triplex Pumps
When it comes to choosing a pump for your semi-pro power washer, your two options are axial cam and triplex pumps. Axial cam are direct drive pumps, meaning they spin at the same speed as the engine, which will wear down faster than a triplex pump, but can be replaced (unlike the wobble pumps found on entry-level models.
Triplex plunger pumps are the highest quality option, offering longer life and better performance. They also include a larger price tag, but if you intend to use your power washer on nearly a daily basis, it's well worth the expense. If the pump breaks down, you can get it rebuilt.
We named this grade of pressure washers "semi-pro" because they bridge the gap from consumer to professional. That being said, our semi-pro units are designed with a lot of 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. The best professional feature you can get would be an engine. The engine is what spins the pump. The pump is what pressurizes the water. So the better the engine, the better the pressure. Look for units with a Honda GX engine.
A nice feature that accompanies medium semi-pro gas pressure washers is a whole mess 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.
