Thanks for the serious answer Ron. I have been readng this forum for almost two months and for a month i have been experimenting with the unit i bought. i am still lineing up the right equipment and getting the bugs out of the equipment I have. i have been working on this project for 8 weeks and still havent done a job yet. I lined up a couple of houses that i am gonna wash for free. when the time is right i will take the chance and try one, believe me when i say this,I WANT TO DO QUALITY WORK. But i have to start somewhere.
