Great Pressure Washer

[This review was collected as part of a promotion.] Pressure washer has plenty of power, adjustable pressure valve is great to regulate for different applications. Only complaint is the chemical syphon did not work regardless of having the soap tip on or not, purchased separate down stream injector that worked great. Best to use a separate down stream injector long term. Very happy with the build quality and performance of the unit.

Great machine

[This review was collected as part of a promotion.] This is the second pressure washer i have purchase, first one was smaller one pressure control went out. This bigger one is great cleaning outside of school building, side walks, and vehicles at our maintenance department. THX

An Exceptional Pressure Washer

After extensive research on power washers, I decided on the Simpson. I love the easy starting Honda engine and the user reviews were very compelling. It was definitely more than I had budgeted for this purchase but it is worth every dollar. After a month of using the pressure washer, I am thrilled with the purchase. If you are undecided, as I was, let me help remove any anxiety. Go with the Simpson...you will NOT be disappointed.
