AMAZING

This is by far the best pressure washer I have ever bought. It is super sturdy and meets all the needs I have. Couldn’t recommend it any better

Best power washer ever!

This is amazing! Cleaned the outside of our house and outdoor furniture great! Excited to get the high reach 2nd story nozzle set!

Great product

I just upgraded from a 3100 psi to this honda 4400 psi and power of this machine is insane. I just did my 1st job with it yesterday and it saved me a lot of time to complete this existing client. 100% recommended.

Powerful

Only reason I didn’t give 5 stars is because it was hard to start the first few times. Followed the instructions to a t but choke needed to be partially closed to start. Once I learned that I didn’t have any issues. Fires right up.

Simpson, Simply the Best

This is my second Simpson pressure washer. The first washer performed flawlessly so when it was time to purchase a second pressure washer I never considered any other brand than Simpson.

Great Value For The Money

The instructions were straight forward and the assembly was quick. For the price, the results were outstanding. Overall, this pressure washer exceeded my expectations.

So far so good

I have always owned Simpson power washers. We recently purchased a lake house and took my other one out there. I ended up buying the 4400 psi and loving it.
