Lots of power
[This review was collected as part of a promotion.] Excellent first impression. The Honda GX390 started easily, the machine feels extremely solid, and the 4.0 GPM flow is noticeably stronger than homeowner-grade pressure washers. Assembly was simple, and all components appear to be high quality. I purchased this for driveway cleaning and small business use, and it looks like it will be more than capable. Very happy with the purchase so far.

Powerful
I bought the Simpson pressure because I wanted more cleaning power for my house siding, sidewalks and driveway. I previously had a 15 year old 3500 psi that the pump died. It didn’t cost much more to buy a new 4400 Simpson than a new pump. There is a world in the cleaning ability of the Simpson. I would highly recommend this pressure washer to anyone that has heavy duty cleaning Donnie Murphy

Great Pressure Washer!
Just bought Simpson Pressure Washer a week ago. Setup was simple, product arrived as advertised and started up with ease. Used for first time to clean a motorhome. Power was plentiful, nozzles worked great and results were great. Highly recommend this product and extremely satisfied with this purchase.
