used my rotovac several times since bying it off John Flynn
Why the hell do you wan t to sell it???
keep it, use it on really Crappy carpets ( when you do come across them)
get fantastic results and jobs from referalls ( like i have)
save your back and BLOODY KEEP IT
well a least thats what i'd do
P.s it will get you much more than a grand in the long run plus you'll still own it
