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.

Superb Quality Built to Last!

a day ago

As a handyman who uses pressure washers on a regular basis, I can honestly say Simpson is definetly the brand you want to go with if your looking for something built to last! Made with durable parts easy to opperate or repair if ever need be, and an engine designed to start right up. Ive always used Honda engine pressure washers because they get the job done despite how bad the job may seem, and Simpson takes it to a whole nother level with all of their unique features they include into their design to complement the engine's overall performance. Showing up on a jobsite with this monster let's not only the customer know, but everyone passing by in the area, that I mean business. Its very presence radiates professionalism and heavy duty application to customers worried about wether or not the work they need completed will be too much for someone they hire to handle. When they see a machine like this showing up to their residence, they immediately feel a sense of ease and comfort come washing over them verses someone showing up with a plug in pressure washer or 2000psi small engine version which screams hours and hours of labor and water use!!
