Hi Lee
I bought AKASO EK7000 4K Sport Action camers about £45.
I will use it clipped to another pole facing the gutter run. This way you can get a better view of what is going on than if the camera is on the gutter vac pole/attachment.
I have the Polarvac. 80 litre wet and dry machine with six carbon fibre poles and assorted tools.
I am ok on ladders and don't mind nipping up when required. Had to do it last night as the weeds had taken over and grown under the tiles and flashing etc. With blocked downspouts you can fit a longer, narrower bit of pipe into the standard tool which fits down the downspout. Very effective and works almost every time. Big root balls, up to two feet long come out the downspout in a very satisfying fashion.
I do a fair number of them. Once you have the kit you automatically target those jobs. I did some student accommodation last week. Ten, four storey old houses all together in Manchester. Cleared the gutters, downspouts and drains with it. Some builders were working on part of the roof and were amazed at how effective it was. {Dumped the lot into their skip}.
When you are out tomorrow, take a look at the gutters. Loads of overgrown gutters around and this wet weather exposes them to the home owner.
