I think the latter option is more attractive to me at the moment to be honest. Thats about sixty kilos of motor to strap into my trailer. Maybe best to see how things go first, if there is enough demand maybe i'll go for it. At the moment it's a lot of dosh to compete with a guy up a ladder.
Personally i dont want to go up a ladder with a bucket and scooping device (argh no hands!) Not safe in anyone's eyes. Thats why i think this is a great idea, it can also be used for conservatory valets, or cleaning inside cars, end of tenancy cleans for example ... think of the uses you can put it too, its not "just" there for gutters.
but again you have to market it's use properly. Im always asking customers if they want their gutters, fascias, and soffits cleaned. and you can do those when its raining \o/ and they are better money than windows
But yes, too much money to pay out for at generator for me atm, i'll stick with doing it when they are in
