Timed myself today, 1930s semi. Pulled onto drive, 7 minutes to set up truckmount, hoses out, wand on ready to go.
Finish, 8 minutes to coil hoses and I haven't got a reel, put wand, spotters away and gone.
I've seen some people in action including some of my ex employees, takes them half an hour to wind up a solution hose on a portable!
