I also own the sunjoe spx4000 and it outperforms this unit in comparison. I am very disappointed as I had high hopes for the spx9006. I contacted sunjoe and they will be sending me a replacement to try out. We will see how the 2nd unit performs when it arrives.
**UPDATE** changing my review from 1 star to 5 stars because of Ronnie@Sunjoe.
First off, I just want to mention that Sunjoe’s customer service is top notch. Ronnie from Sunjoe contacted me personally to help address my issues. He was extremely helpful and patient as we made attempts to trouble shoot the issues I was experiencing. Unfortunately, the original unit I received was defective.
However, after I received the replacement unit a few days later my opinion on the machine changed. I was now getting a reading of 1200psi of idle pressure and about 900psi running pressure with the trigger pulled. The user experience of washing my vehicle is amazing. I am now getting the exact pressure needed for washing my vehicle with the added benefits of increased GPM.
I am very satisfied with this unit and especially satisfied with Sunjoe’s customer service and warranty process. For the price, I think this unit is beyond worth it because Sunjoe backs their warranty 110%.
