Purchased it for my parents 2 story house. Connected it to my 2200 PSI Yard Force pressure washer and there was not enough pressure to do the job for a two story house. Purchased a extension pole that did the job.
Michael Does Not Recommend This Product
The folks at Generac described this product as "Works best between 2700 to 3200 PSI; Rated up to 4200 PSI maximum".
While I'm sorry your 2200 PSI Yard Force unit wasn't able to deliver the performance you were expecting, we will continued to use the manufacturer's specs.
