***UPDATE***
since the weather finally broke into the upper-30's today with sunshine, i tried out my new pressure washer and foam cannon.
one words pretty much sums them up....awesome!!
the pressure washer has more than enough power to do what i want with it. it assembled easy, i added the engine oil to it, and it started after 2 pulls.
i also splurged with quick-connects for the garden hose, PW pump to the PW hose, PW hose to the gun, and quick-connects for the lance/foam cannon (for ease of swapping them out while washing).
the foam cannon, well, i had a grin from ear to ear while using it!!
