If you rely on a pressure washer to make a living then you need to invest in a commercial pressure washer. Below are the best 2 – one has a direct drive pump and the other a belt driven.

Commercial Pressure Washing

Commercial Use

A commercial pressure washer is defined by its power first and foremost. It must provide at least 16,000 cleaning power units as defined as PSI x GPM.

Second, there are two types of commercial pressure washing:

  1. You spend only half the day pressure washing (less than 25 hrs per week)
  2. You spend entire day everyday pressure washing  (30+ hours per week)

If you are type 1 and spend approximately half the day pressure washing you’ll be fine with a pressure cleaner that has a direct drive pump.

Direct Drive Pump 

  • Pros: Compact design, lower cost.
  • Cons: Reduced lifespan – prone to overheating and excess vibration.

If you are type 2 and spend the majority of your day everyday pressure washing then you should get a pressure cleaner with a belt driven pump.

Belt Driven Pump

  • Pros: Longer life, lower RPM, belt absorbs vibration, won’t overheat.
  • Cons: More maintenance, higher cost and less efficient.

Now that you know which type of commercial pressure washer you need, let’s take a look at the best of each type for most people.
