Customer review summary generated by AI, including incentivized reviews.Very powerful
Opened the box today, easy set up, had to put in engine oil 10W-30. Crankcase oil already add before boxed. Very heavy duty hose included 50 ft. I bought addtional 100 ft extension. I have a very large driveway and basketball court and due to the 150 ft of washer to wand hose, I didn't have to move the power washer once. Zero degree apeture attachment (red) allowed me to reach mud dauber nests 23 feet up in entryway.

Beast
Researched many pressure washers before pulling the trigger on this one. This thing is a beast it cut my time pressure washing in half. Highly recommend spending the extra for this machine.

A rock solid pressure washer
[This review was collected as part of a promotion.] As soon as I unpacked my pressure washer it was obvious that it was constructed from quality materials. Everything about it looked solid and well built. I'm certain I will get years of service out of this machine with proper maintenance. It's everything I expected and more.

Don't spend your time on line or on the phone.
Haven't got it yet. Lowe's had to reorder due to giving it to the wrong customer. Now they can't give me a new delivery. Terrible!!

Good pressure washer
I love the machine, it’s quite reliable but it sure does drink gas. If you wanted to start your own business I do recommend this!

top of the line stuff!
I bought this machine to start my first LLC, business, and I'm so glad I did. The unit is so powerful, and makes downstreaming an easy option with the built-in injector. From the Honda motor to the Triplex pump...top of the line stuff!

Good purchase.
Just the size and capability I was looking for. I think the Owners Manual is lacking some information, but I figured it out myself.

Very Good Power & Water Flow
I received my Simpson PS60843 4400 psi 4 GMP pressure washer on 6-2-2026. Installed oil and gas. It fired right up. Great pressure! Cleaned pitted concrete driveway. And good water flow at 4 gpm.
