I've been doing a bit of online shopping and spent more than the price of a chepo sj4000 cam on a selection of silicon bends to be able to make up a gutter vac nozzle from silcon bends and aluminum tube to be able to fit in these type of domesitc gutters.
I just hope now I have not wasted my money as I don't have time to get an all aluminum fixed heads made for that job nor mess about making them from plastic plumbing pipes/bends that both types will probably get constantly blocked anyway.
At least the job is worth the added expense and all the messing about or I would have said sod it...Oh the joys of gutter clearing
