Holy power Batman!
This thing has way more power than my old one that finally gave out after 20 years. Hopefully this one lasts even longer.

Reliable and Easy to Use
[This review was collected as part of a promotion.] The pressure washer is easy to start and use. Have another Simpson at my other house and it’s been very reliable so I bought a second one.

I bought this 9/15/26 and could not wait to use it. I used it for first time today and it is spectacular, good pressure and easy to handle. I did not take pic of using it.

Driveway looks brand new again!
We love the pressure washer. Only one concern. We had to use a pressure washer hose from our old one before we could get it to work. The brand new one is defective. We would like to request a new one to be sent to us immediately. Thank you!

Perfect
Its about perfect in every way. Easy start, light enough to pick up and put in my truck bed and has enough power to blast away most anything

Driveway looks brand new again!
I bought this on 9/8/26 and it works great. Our only concern is that we had to switch out the power washer hose before it would work. We need a new one sent to us immediately and then we will be a satisfied customer. It works great with our hose from other power washer.

Very nice pressure washer for the price.
Perfect for home/auto/boat. The motor and pump are a great combination. The pump is a larger (serviceable) commercial style triplex pump. The engine holds a ton of fuel for doing home maintenance. It’s not terribly loud, the un-loader valve works great, and the cart makes moving it around easy on uneven terrain or through thick grass.

Nice machine
Works great, it is the perfect size machine for around the house and more.

Great Machine.
Machine runs and produces great power. 5 stars for that. However, the hose that comes with it is extremely stiff and hard to maneuver.

Just putchased
Just assembled. Easy to do. Have used Simpson products in the past and look forward to this one.

area for improvement
This is the second Simpson I have purchased and find them to be a very good machine. This time I found it difficult to assemble out of the box. The handle just would not slide down the post far enough to make sliding the bolt through the holes. Had to use a drift pin to align. Other than that worked great when fired up.

A Beast
This is my 2nd Simpson 3700 power washer. It’s a beast, cleaning red brick, limestone, and concrete. Super rugged and always starts on the first pull, even after wintering in the garage. Great Product 👍
