CFR?
I've got three of them... 7" stair / fabric partition tool, 3" normal tool and the very rare "little digger" 1 1/2 " detailer (brilliant for the front and cuffs of suites).
I've also got one of the 11" FOUR jet CFR push wands (again, brilliant).
I've got the CFR machine to match but if you are using a truck mount, then the benefits should be greater still.
