you can use a car wash brush (they do also state they can be used for windows) that you get from most car shops.
it will prob need a simple but easy mod doing to it. from the centre where the water sprays out, remove 4/5 of the bristles that are fixed in. this is done by pulling them with some pliers, the whole clump will come out in one piece.
when you have done this, make an enlarged hole in the middle of the slit where the water comes out, about 1/4inch size. then get some small pipe, i have used the really small pipe from an old RO unit, about 1/4 inch wide and feed it into the hole and keep pushing untill it goes a couple of inch into the shaft of the pole itself.
the first couple you do take a bit of time, but when you know what you are doing you can do it in 5 mins literally.
i have just got a brush brand new from a car boot for a fiver
, this is alot cheaper than getting a glass fibre pole from elsewhere. if you are careful with them you easily get a year from them.
ok not the most proffessional looking pole but it works great and it saves you a few quid, which is what you want!!!
