Rated 5 out of 5 by from Great pressure washer; just a few suggestions for improvement I purchased this for home/farm use to clean vehicles, tractors, etc. I am very happy with the set-up, use, and performance of the pressure washer. I have a few nit picky comments that in no way detract from my opinion of the unit. 1. No where, that I can find, is it listed what volume of oil the crank case can hold. I assume the 16 oz of oil packaged with the washer is the max but it would be nice to list it clearly in the specs. 2. The garden hose input connection and the washer hose output connection are ever so slightly too close together. Spreading these apart so you could completely grasp each tightener without hitting the other connection port would greatly improve the set up/tear down experience and decrease customer annoyance. 3. The storage area/hook for the pressure washer hose is a little awkward to use and does not allow the hose to lay nicely when connected to the spray gun. it could definitely use a redesign. 4. While you are at redesigning things, the soap aspirator hose could use a storage place for when it is not in use instead of just having it dangle randomly. It would be really slick to include some sort of universal cap that would just screw onto a one gallon soap bottle and put the end of the aspirator hose at the bottom of the bottle.
