We bought one in October last year and im well impressed!!!!!
We also did a flyer drop just for gutter cleaning and made our money back for the Vac, the leaflets (designed and printed) and distribution in about 6 weeks!!!!!!
This year have seen us price some silly priced jobs for the time needed to complete, like £150 for a gutter clean which took just over 2 hours, and £35 for a job which took 10 mins
I would say its a well worth while investment and worth every penny.
We wouldnt go back to using manual methods! Get it you wont regret it.
The only prob is making sure you can get power so people need to be in or you need to know if they have external power points.
We're gonna get a Genny this year that way we can do them without needing customers to be in.
