Very nice machine

Pressure washer is perfect. Cat Pump works great and the machine is light enough to put in back of the truck. You can actually close the bed cover to keep it from getting stolen.

Just what I wanted!

Chose this unit because I wanted the Honda motor & the CAT pump. Easy set up out of the box. Well pleased after initial start-up & use. Confident it’s going to be a great unit!

Best of all features for the Homeowner

Powerful and efficient for all my household needs. If you've ever saw a hose and wand get loose and go wild this is what this machine is capable of. Better hold on tight because this is capable of going wild for sure.

Self Reliant Women Quickly Decides via Helpful Comments / Reviews

While being proactive with busy life style on a budget, I am confident my research and money invested with Honda Engine (long term), CAM wand (popular), & aluminum frame (rust prevention) will make my Pressure Washing Projects fun. Thank You :)

Small but mighty

I wanted a pressure washer that was powerful enough to do jobs but light enough I could easily lift it into the trunk of my Toyota Prius. I found it in this one! The first time I used it a couple nuts came off and bolts were loose. I was thankfully able to find them in the yard and tighten them up. I only use ethanol free fuel in it. I also upgraded to a longer hose.

Great engine, great pump

the on-line information list the unit at 3,400 PSI. The manual indicates 3,200 PSI and the pump mfg says 3,000 PSI. The actual static pressure is 2,900 PSI The unit needs a un-loader. After 2 pulls to start, there is so much back pressure you have to trigger the gun to get it to start. Very un-safe!

Except for shipping glitches. Great pressure washe

I bought this pressure washer about three weeks ago. It came in about 4 days which was pretty fast. Why it arrived the box it came in was all beat up. It only had one pi ce of tape across the top and bottom. The plastic on the pressure washer gun was broke and the wand bent. And it was missing one of the rubber foot. I called water cannon where I bought it and told them about it but they could care less. ( I will never buy anything from them again). So I called customer service at Simpson and they were very nice. They sent the parts out in three days. As for the pressure washer I have used it theee times, it is amazing. A lot of power and starts on the first pull. The Cat and Honda engine are awesome. If it wasn't for the packaging issues I would have given this pressure washer five stars. Simpson needs to look into their shipping department. All in all it is worth the money.

Performed as Eixpected

Just replaced my old system that blew out the pump. Motor was still running fine but the Cat pump was pricy. It lasted over 10 years so I wanted the same Honda motor and Cat pump. The new one was a little stubborn to get started for the first time, but once it started it performed perfectly. I expect to get at least 10 years from this machine to as well. The aluminum frame makes it a bit lighter and smaller which makes it easier to haul around.
