Karcher K5 Pressure Washer vs Greenworks GPW1501 Pressure Washer

Analysis:

The Karcher K5 Premium (2000PSI/1.4GPM) is a great Pressure Washer for its $227 asking price.

The Greenworks GPW1501 (1500PSI/1.2GPM), however, while a reasonable product for $89, doesn't stack up against its competitors quite as well. If you're considering Pressure Washers in the $95 range, you might want to check out some better options.

Expert Reviews, 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 very large patios and for doubling up on other uses around your home" in its "Best patio cleaner: Rid your patio of moss, mould and dirt, from as little as £8" roundup, which points toward it being a good Pressure Washer.

As for the Greenworks GPW1501 (1500PSI/1.2GPM) - it was really well-received by reviewers at TechGearLab, a great source that's known for conducting high-quality in-depth testing. It performed great in its "Best Pressure Washer of 2020" roundup and was named its "Best for Light Duty", which, on its own, makes it a product that warrants a closer look.

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.

Then we checked which sources liked these two Pressure Washers best and found that the Karcher K5 Premium (2000PSI/1.4GPM) got its highest, 9, review score from reviewers at Top Ten Reviews, whereas the Greenworks GPW1501 (1500PSI/1.2GPM) earned its best score of 9 from Top Ten Reviews.

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 9.0 and 7.9 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.
