Well Clive I hope you haven't ruined the awning of your caravan by steeling that angle Joint from it Lol
Its looking good, what it needs now is a brush following the scoop and following the brush a hose to rinse clean.
In a few years time we 3 are going to be sat around our PC's laughing at the beginnings of the gutter scoop inventions, we may laugh but they will become a very popular item in any wc toolbox but I hope not the house holders tool box, with all this rain were having my gutter cleaning services this year have tripled over last years work and that will dwindle if it becomes a domestic product.
I only need my simple gutter scoop to remove the extra garden type of weeds from the guttering, once that's removed I then get the lance out.
One thing I do when its lance time, is to remind the customer to remove animals children and them selfs from the area for safety reasons, you can also do this if you produce your electric gutter scoop.
Good luck and keep it going.
