    • Great pressure washer!
Size: 4200 PSI Honda GX390
This power washer is well worth the money. It has a downstream chemical or product injector so the product never enters the pump. I filled the engine with the oil that was provided, put fuel in the tank, hooked the hose up and purged the air from the high pressure line and nozzle, and it started right up. Always read your instructions before using or you’ll end up destroying your pressure washer. Oh! There is also a little red plug in the pump the has to be removed (vent Plug) for the lubricating oil reservoir. Great product with plenty of power! ... show more

    • Excellent piece of machinery.
Size: 4200 PSI Honda GX390
I have two diesel driven hot water pressure washers, both are skid mounted and each cost more than $10,000 so when this washer arrived yesterday I was immediately impressed by the way it has been put together. The belt drive system is very important for engine life. It is excellent, very powerful and the engine is not stressed at full pressure. I used it initially by dialing down the pressure and then winding it up after time. My only disappointment is the way the soap system works, it can only be used with a large tip, I am used to using mine at any pressure and with any tip. Have not tried it that way yet but will soon. It also does not have a on off tap for soap delivery. A pressure Hague would have been a nice addition, I will do that myself. It also did not come with an engine manual, I had to download that myself. You will not be disappointed with this machine, if you take care of it and do the servicing required. ... show more

For the first week, this worked as described. We've had no issues and the high pressure really cuts working time.

Size: 4400 PSI CRX420
Very powerful, portable unit. The location of the pump makes it great to keep the hoses away from the hot parts of the engine. The trigger handle could be a little better to allow access to the nut that connects the hose, but this is pretty minor.

Got the machine, set it up and the recoil start was stuck. Called Simpson and they just said take it to a service center. No chance. Refund. Maybe it’s a good machine, don’t they claim they test them?...,

Perfect machine, powerful, effective, and quality throughout. The Honda motor starts right up and the pump is a piece of artwork.
