depends what your using it for (and don't say gutter cleaning lol) as in just residential or mainly commercial.
For me personally i use a basic Clark vac with genny as it was small enough to fit in the van and could unload and load by myself weight wise and is fine for your run of the mill residential.
Some may disagree but i found it powerful enough, there are a few more options about now a days regrading vacs etc but 1 thing i would highly recommend is to get carbon fibre poles as the normal ally ones are heavy after a while especially if your working over a conservatory,
and at your age you need to look after yourself
