when i started it was ups only,then when i started making my own pure water ,instead of buying it off someone i was doing the whole house with the pole,don,t forget the pole is only another tool to use in the job,you,ll come across some houses and windows,that would be quicker trad,i even get the ladder off the van sometimes if there are like 3 or 4 windows round the back of a property,and i can,t be botherd to drag 30 or 40 mtrs of hose round some dirty old alley,full of rubbish.try both ways then do the one thats the best and quickest for you..good luck...kev
