Great pressure washer

I bought this pressure washer to replace my old pressure washer. Simpson pressure washer paired with the Honda engine is a very good combination. I am a repeat buyer. Do recommend.

The power

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!

Pressure washer

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.

Amazing!

Perfect machine to start with! Easy to use and get around. I love the warranties and that it has a Honda engine. They last forever as long as you care for them properly. The psi and gpm with a 16.5 surface cleaner works like a dream. Highly recommend thismachine

Nice looking, but poor handle design

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.

Simpson 4000psi Honda Gas Pressure Washer

After a couple disappointing electric pressure washers I decided to go big and get a Honda 4000psi pressure washer. Great power, easy start, and fantastic results. Now have my own touch less car washer with the Simpson soap suds bottle adapter. Ive got multiple large excavation equipment and trucks, two houses to paint, and a couple 45ft containers to change color. 4000psi with adjustable pressure gives me unlimited options for cleaning going forward.

Pressure Washer I’ve been Needing

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.

So far great!

Purchased the Simpson/Honda 4000/3.5 recently to replace my 13 year old Ridgid/Subaru 2.8/3300. So far, I have used it multiple times and love it! Great power, starts on the first or second pull. To make an oil change easier it would be great to have a Drainzit hose installed.
