Love the amount of power that it has for the price point. Oil dipstick doesn't have high or low marked on it...so hopefully we guessed it right.

Just received it and put it together, tried it out for a few minutes. Very powerful, and strong pull back when trying to start

My husband races dirt tract and this Simpson pressure washers cleans up the car after every race! It has awesome power!

Everything about this pressure wash is very professional. If you looking to upgrade to higher gpm without breaking the bank, this is the one!

Great machine runs great. Put together very well. Runs very smooth I'll use use it tomorrow again on my pool deck

Great pressure washer. Bought a year ago and only a few small problems. Overall a good bang for your buck.

Just took it out of the box, but I did the research. good reviews, looking forward to using on a consistent basis

This machine does what it's supposed to! Cannot wait for this drought to be over so I can put it to full use!

I got my pressure today. Easy assembly. Ran it for a short time with my surface cleaner. Seems to work great.

Super reliable, easy to use plus super easy setup.. sturdy, well built, and also the best 4gpm money can buy
