hi cleewindows,i just had a look at the vac on ebay,it looks good i am tempted to get one could you tell me if you use a generator to run it, if you have picked up much work since you got it and what is the maximum height you have used it at i have a few pound to spend and am undecided wether to buy a diy guttervac or spend it on advertising/website,etc and would appreciate your advice-thanks
