The engine seems very robust. I love the triplex pump. I was kind of bummed they sent it without the spray wand. I'm still waiting to hear whether they will send it to me or what

My wife and I both have used this pressure washer and love it. It is easy to start if you pull the trigger on the wand and release the pressure. So far no problems.

I bought this PW to clean hard surfaces like concrete, brick, stone, etc. I use a surface cleaner and it really does a super job! I would recommend this PW.

I bought this about a month ago. I am very bappy with the unit so far I had a couple little issues with shipping, but Simpson took care of it right away. Definitely recommend

I bought this pressure washer to do the concrete sidewalks at my house and to rinse my saltwater boat trailer after a day of fishing. It is incredibly powerful. I'm able to quickly finish the chores with power to spare!!!

Only used once so far and has exceeding my expectation. Wish it had a better wand and hose. 4 stars because the pump was scuffed up when I unboxed it.

We purchased this fine machine with the extra 100ft hose and concrete scrubber and could not be happier... excellent quality / powerful pressure washer

I've had about every electric pressure washer known to man, and let me tell you - this is the DENALI 3500 😂 it means business.. and look forward to years of use with it!

I bought this two months ago and have used it daily since great powerful pressure washer. I have no complaints at all!! Fires up on the first pull every time.

This thing is big, and heavy. The only reason I am giving it 4 stars instead of 5 is because of the typical terrible handle and lance holder. Other than that expected deficiency, setup was easy and started easy, sounds tuned. The power is something you have to get accustomed to when in use.
