Hi Justen, the Harris pole really is almost too good to be true! fantstic value for money!! and as good as many poles costing £100's more!! Thats why have been singing its praises in this thread!!!
I have two harris poles, one has a lightweight vulcan brush with fan jets, and the other is also a vulkan brush but with pencil jets, I like them both, I'm still undecided as to which I prefer. If you are going to put an extension on the pole like I have then you need to get the lightest brush you can get, and fan jets would probably be best because you would probably want to rinse with the brush on the window at 3rd floor level!
