I remember more like two feet off the end of the
nozzle. With my trailer roof, we used the 2 inch
PVC to get farther into the roof. That was very
helpful.

You do really need at least two workers. One to
tend the machine, other to guide the nozzle.
Little walkie talkies are a help, but the machine
is noisy.


why use a walkie talkie, just 2 cell phones with unlimited talk and text.
