Q: Use the unit last night for the first time. Very powerful. The 50-ft hose is a bit stiff and hard to manage. Can you recommend one that would not be as stiff?

A powerful machine at a reasonable price point.

6 years ago
The Simpson PowerShot 4000psi pressure washer with Honda pump is a workhorse of a machine. I was pleasantly surprised to see that it had the power to blast the grime off my driveway removing many years of over spray from DIY projects and baked in oil stains. Additionally, I purchased through another vendor a Foam Cannon to make short work of various cleaning tasks including the Tractor, Trucks, and even the brick on my house. I provided five star feedback because it does everything as advertised at about half the price of it's competitor from another well known pressure washer brand. My only complaints thus far are as follows: no pressure gauge to tell what level you have set the pressure to; pressure relief valve is very hard to turn both under pressure and without pressure; the hose is very stiff, just a step better than the cheap pressure washers; the handle is far too short to be useful; and finally it would be nice if there was a tank for chemicals. We have no way to get a bucket underneath the level where it needs to be. But, a gravity feed tank would make things much easier.

Wow...what a disappointment.

5 years ago
Ran for a total of less than 60 seconds - with the trigger pulled before that was a gunshot loud pop and the pump blew with a chance flying across my pool deck. Good thing there was nobody in the way. Called Simpson and their response was that they could let me know the service center near me....no thanks. Thankfully, Tractor Supply took the unit back without question and even apologized for the inconvenience. I research long and hard before deciding on this unit. Not sure what I will purchase now - very concerned about Simpson quality at this point.

Fantastic pressure washer

This things a Tank!

a day ago
Upgrade from my old 2300 psi pressure washer that could only pump 1.7 gallons a minute if my memory serves me correctly. This thing is doing over twice the gpm and almost twice the psi. Even though this thing is a lot heavier so it’s harder to transport. It’s really easy to maneuver for its weight. The only thing I wish it had was a gauge for when you adjust the pressure. It’s all just a guess without a gauge. The only time that’s really a concern is when you use attachments that have a lower psi rating than 4000psi. Overall I’m very pleased with my purchase and I’m sure the Honda engine will keep on working well into the future.

Outstanding Quality and Value

Pleasantly surprised with the detailed written instructions and manuals that came with the unit nicely packaged in a box on a pallet. Most products do not come with writtne instructions anymore and require website access to get the procedures for set up and operation, but this unit comes with full set of manuals and additional quick start reference guides to make final assembly and start up really easy. After following the instructions, the unit started right up and runs really quiet and smooth. The engine does not seem like it has to work really hard to deliver the fantastic pressure and flow.
