ive been hearing about this x-jet, what are the pros and cons about it, it may be covered in my last post but im having a problem with tall houses, i get the chemical to soak on the top of the house, but when i rinse it seems like i never touched it, i have a telescoping wand and belt i bought, like 300 bucks, but even with the belt that thing is a nightmare, almost like i would have to get on a ladder with a scrub brush.... but then that would defeat the purpose of the power washer right? and after i let the chemicals sitfor 5-1 mins, i still have to use a 15 degree tip to wash the dirt off, we're kinda new to doing houses so if anyone else has had this problem in the past please let me know wat im doing wrong...thanks alot
