The power and the monster hose really make this product very nice. Also came with the downstream injection works great for adding soap without messing up the pump.

The Honda engine is super reliable and the power is incredible. It does everything I need it to and then some. Follow the maintenance schedule and this thing will last for years.

I have always owned a power washer and the Simpson 4000 so far beats them all in workmanship and pressure. There is no question that it’s a well designed machine

It is exactly what you pay for and a little more. It has all the attachments you need to get any job done. Only issue was figuring out how to start it. Me having no experience was a little bit of a challenge. If you throughly read the instructions provided you will be all set.

I recommend using this product with a lower discharge pressure setting to start then dialing up to 4000psig if necessary. Also, remember to protect your pump seals with the spray in connector designed for your pressure washer after you are done for the day!

While the machine looks great, I have not even started it up yet. I am disappointed at how loose the handle is, even with the bolts turned as tightly as possible. The handle tube diameter is too large for the receiving tubes that are part of the unit's frame. For the cost of these machines, having a handle this loose seems ridiculous. You can see in the photos the difference in measurement when applying pressure and not applying pressure to the handle. I'll come up with some way to improve this on my unit. I hope the performance makes up for this design flaw.

Recently purchased the Powershot 4000 psi pressure washer and it has exceeded my expectations. I’ve only had smaller, electric units before, and the additional power of this one allows me to do all the things the others didn’t (cleaning high parts of the house, etc.). This washer seems extremely well made and I expect it to meet my needs for years to come.

This pressure washer has all the power needed to clean large areas quickly and efficiently. The pressure can also be adjusted to clean surfaces that do not need the higher PSI.

Bought this to replace my 20 year old pressure washer and what a difference. This thing is a beast and will handle most anything you need! Would buy again.

Easy set up out of the box. Engine started per instructions. Nice long 50 ft hose with quick disconnects at either end. Power is more than efficient for heavy duty cleaning around the farm.
