Good water pressure.  $2 = 6 min. Cons- "water pressure gun" rubber tips come OFF -can scratch car paint. Had to back out since a car blocked me forward-then a hose (which I put back) caught my car. Hispanc guy gets angry/curses. The ceiling 360 degress brush holder gets jammed. 1 is bent. Stalls get muddy.  Vacuums not strong.
