10 Most Popular Pressure Washer PSI’s (And The Best Pressure Washer For Each PSI)

The Society for Protective Coatings classifies water cleaning technology according to the following PSI ranges:

  • Less than 5,000 PSI is low pressure water cleaning
  • 5,000 to 10,000 PSI is high pressure washer cleaning
  • 10,000 to 25,000 PSI is high pressure water jetting
  • More than 25,000 PSI is ultra-high pressure water jetting.

But when it comes to everyday use the most popular PSI pressure washers are all less than 5,000 PSI.

Which PSI pressure washer do you think people are most looking for? I went and looked at the data for Google searches and here’s what I found are the 10 most popular pressure washer PSI’s.

Here’s a chart of the 10 most popular PSI’s and how many searches each gets per day:

Popular PSI Pressure Washers By Searches

The top 2 of the top 10 account for 46% of the daily pressure washer related searches with “PSI” contained in the search. At first I was quit surprised as I thought the smaller medium-duty pressure washers like 1800, 1900 and 2000 PSI would have dominated. Then I went over to Amazon and it made sense…Here’s why:

There are around 600 pressure washer options in the 3,000 PSI and more category. And there are less options in all the other categories that are less than 3,000 PSI, combined. 

Now that we’ve looked at the top 10 PSI’s people are interested in – let’s look at the best pressure washer for most people to buy at each PSI. We’ll start with highest PSI and work down to the lowest.
