I now have two of them with all of the extra disconnects plus.
I use one at home for my car. Sometimes with buckets and sometimes just a rinse, suds, rinse, QD for quick washes with PSS or 901.
Use the second one on my fishing boat that lives in salt water. Man I love fiberglass instead of wood. Rinse, suds, brush off the blood, rinse, beer, go home, nap. I used to use Simple Green and a scrub brush and wonder why it never stayed shiny. Now use PSS and the shine stays on. No more power scrubbing, etc. I would give up the car one before this. The other wharf rats all want to use it on their boats.
