Since the bottle is emptying, then the pick-up tube must be installed.
How are you measuring the amount of shampoo?
- long squirts of the 16oz bottle. Usually 3-4 squirts. Ill get a measuring cup for next time.
Are you shaking the bottle really well to mix the shampoo into the water?
- the first time I used it, I shook it really well. Per CS from Adams it only takes 2 or 3 turns just to mix the soap around.
Did you notice any difference when the knob is turned all the way to plus and then all the way to minus?
- no, it was the same as my first go around.
Are you adjusting the front nozzle to get a medium-wide spray pattern?
- yes. I have it on a medium wide like most videos
Is there a pressure adjustment on your pressure washer?
- there is an RPM lever, should i have it on full speed or more towards the low end?
Can you post a pic of the foam cannon in use?
