if you get loads of enquiries then defo worth getting one especially if your taking someone on, its a lot easier with 2 people
regarding the poles im not sure how long an sl2 would last with the amount of debris going through it but ive had my omnipole set for a few years now and theyve still got loads of life left in them, ive got an sl2 but couldnt bring myself to use it for gutter vac although it would be lovely and light, i have had a quick look round for something like the gangster pole but havent come up with anything yet, i went to the show and think it was grippatank that had modified gardener sl2 poles designed for gutter vac but was about, just found the grippatank price list and there selling' gutterlite' 55ft pole set for £1749.00 plus vat
how will you transport it are you getting a bigger van or getting a trailer?
when using the gutter pole your not moving it like a window cleaning pole so the weight isnt so much of an issue although reaching awkward sections of gutter would be a lot easier
