I bought this a month ago added a motor minde to keep track of hours for maintenance Started first pull and lots of power. Power washed my shed wit no problems.

I have always owned a power washer and the Simpson 4000 so far beats them all in workmanship and pressure. There is no question that it’s a well designed machine

I have used this three times and only had about six weeks. starts up on the first pull every time not a hick-up. no other choices to be made Simpson is awesome

I bought this to replace a smaller unit that wore out. Very pleased that I upgraded to this commercial grade washer. I have some getting used to the higher output. Very nice.

This unit is top quality compared to other units in this price range.

Great strong power washer. Easy set up and simple to use.strong pressure, engine very good

Dependable with Honda engine. Well built and easily assembled

Great product works well we did amazing work for are new llc

I bought this power washer about 1 year and it's working great. Starts easy

Talk about a powerful machine! Love it and can’t wait to see what all I will clean with it!
