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 product

[This review was collected as part of a promotion.] Bought this a few weeks ago and finally got to use it. Worked very well and was easy to set up. The pressure is awesome on this.

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.

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

Great pressure washer

3400 PSI is a game changer. Also … this is a first … put oil in, put gas in, pulled the cord … one time … it started; one pull, first time ever used - STARTED. That has never happened with any piece of equipment!!!

Disappointed

This is my second PowerShot, and I am disappointed. First, the carriage has been redesigned to eliminate the shelf behind the motor. Second, the fuel filter and gasket were missing. Third, the soap dispenser is not working so I will have to take it apart to see if the ball is stuck.

Powerfull however a major flaw

I am impressed by the easy setup, immediate start upon pulling the cord, powerful jet with any tip, size etc. However, after a short break for a water, when I bent to pull the cord my left hand naturally touch the metal top surface of the muffler's cover. Big mistake.Lots of pain. My point is: if that surface gets so hot and is a natural place where the operator will touch, why Simpson did not place on top an insulation protection to avoid an accident? why the warning show on top is in the same black color as the metal surface?

Shockingly disappointed

I was really excited about this unit, but unfortunately had issues with it straight out of the box. I still haven't been able to use it. I'm no newbie to power equipment and was sure to follow all directions and start up procedures. Upon first start up, my unit leaked (more like spewed) water from the chemical injector port located on the pump and the adjustable pressure regulator knob. I will now have it to take it in for warranty service and haven't even had a chance to use the thing. Was really shocked to see such poor Quality Control in such a leading, strong brand of pressure washers. Very disappointed.
