The Spruce, a review site with a history of doing objective hands-on testing, has great things to say about the Karcher K5 Premium (2000PSI/1.4GPM). In fact, it's "Best for Cars" in its "The 11 Best Pressure Washers of 2023, Tested and Reviewed" roundup, which points toward it being a good Pressure Washer.

As for the Greenworks GPW1501 (1500PSI/1.2GPM) - TechGearLab, a source that conducts reliable hands-on testing, has featured it in its The 3 Best Pressure Washers of 2023 roundup. However, it didn't make it to any of the top spots.

We examined all of the review data that we could find and first took a look at sources that reviewed both of them, like Top Ten Reviews, and found that they haven't shown a preference for either product.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Pressure Washers on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Pressure Washers being 7.5 out of 10, whereas the Karcher K5 Premium (2000PSI/1.4GPM) and Greenworks GPW1501 (1500PSI/1.2GPM) managed averages of 9.3 and 8.5 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Karcher K5 Premium (2000PSI/1.4GPM) vs. Greenworks GPW1501 (1500PSI/1.2GPM) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
