Very easy to assemble, and it starts on the first pull. I have cleaned my brick pavers, basement floor, and 2 tractors, and it did a fantastic job. I read other reviews about it being difficult to start, I think they need to read the instructions.

I've used my machine 3 times now in the last month. Very satisfied. Very easy to put together. Starts on the first pull. I just ordered all the attachments. Overall pleased with machine from price to function.

the simpson name says it all..had another model for 8 plus years..it finally gave out..so im giving this 1 a try..great power but it takes a few pulls to get it started..so far so good though

I bought this pressure washer to do the concrete sidewalks at my house and to rinse my saltwater boat trailer after a day of fishing. It is incredibly powerful. I'm able to quickly finish the chores with power to spare!!!

I brought this to pressure wash my driveway. Did a great job on my pavers. Lots of power you have to really hold one when you hit the trigger. I love the way you change the nozzles on this .

Bought this unit on mother's day. Had a 3600psi excell with the 13hp Honda engine,l used that unit for 19 years. Used it commercially and it finally gave out. So far this unit is working great.

I bought this about a month ago. I am very bappy with the unit so far I had a couple little issues with shipping, but Simpson took care of it right away. Definitely recommend

My wife and I both have used this pressure washer and love it. It is easy to start if you pull the trigger on the wand and release the pressure. So far no problems.

I purchased the 4250 for the 4 gpm capability, I love everything about the machine, definitely a great purchase if you are starting out with a pressure washing service.

I haven’t had a chance to use it much because I just got it but let me tell you this it has plenty of of power, it cleaned blackened mossed over mortar between bricks like it was nothing something my old pressure washer wouldn’t do.
