Thanks Great to be here. I actually used one of those Troy Bilt the other day at a friends house..... I can say it got the job done alright, the second strongest tip was on it. I cant remember red or yellow, but it did alright. It couldn't get the baked stuff off the exhaust and what not, but I imagine their "extreme" tip or 0 would take that off. Also tried to get all the mold off his vinyl siding and it did nothing, once again, Maybe the stronger bit would work. Wish I would have tested that out so I could help ya. Also, i don't know what the Troy Bilt one cost But....
another friend of mine just purchased a RIGID from home depot with subaru engine and cat pump for something like $600-650 I believe. This one works great, just like the $900-1200 professional ones I have used in the past.
