Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise this pressure washer for its exceptional 4200 PSI and 4 GPM power, reliable Honda engine, and durable CAT pump. Reviewers consistently describe it as a powerful workhorse delivering professional-grade cleaning on driveways, concrete, and decks, with many noting it far surpasses their previous 3000 PSI models. The Honda engine starts reliably on the first pull and runs quietly, while the CAT pump resists wear effectively. Users appreciate the aluminum frame's rust resistance and solid construction. Most find it easy to start, assemble, and operate, with phrases like "worth every penny" and "last pressure washer I'll ever need" reflecting deep satisfaction. A few report isolated concerns, though nearly all consider this the gold standard they've been seeking.

The pressure washer was not assembled correctly and had to be serviced before I could use it.

Great new toy
I’ve been very impressed with this pressure washer. It was easy to assemble, starts up without any issues, and delivers strong, consistent pressure. I’ve already used it on several cleaning jobs and it has performed great every time. The build quality feels solid and it’s an excellent value for the money. I would definitely recommend it to anyone looking for a reliable pressure washer.

Bad Out-Of-The-Box
Would Not RecommendAfter following instructions and requirements to the letter, the Honda motor started on 2nd pull and ran like a champ. The pump did not. Never would kick in. Instructed to take to designated repair shop that hasn't even looked at it at 3 weeks and counting. I have met 2 others with the same issue after unpacking this Lowe's supplied product. The quality just isn't there.
