Getting over a conservatory roof is childs play, no resting on the gutters for support, no straining when you have to lean the pole sideways when fully extended.
The superlight brush on first use appears to be very good indeed, amazingly light and very effective.
It's my first "brush" (pun intended) with needle jets too, so far it has been fan jets all the way and I have to say that I am impressed with the needle jets, it also appears I can reduce my flowrate and save water...I think, but will need more time to assess that aspect.
Nowt wrong with fan jets I might add, I think it really comes down to your own personal preference, but you do need the fan jets set up properly for maximum efectiveness.
An external pole hose gives you far more flexibility than through the pole, regardless of the pole you use, telescopic or modular, it allows you to use only the pole sections you need for whatever height you happen to be working at.
You can either twirl the pole when extended to wrap the hose around the pole, or do as Alex does and use a couple of strips of velcro to hold the hose close to the pole, and as Jeff says, it also allows you to swap brushes or goosenecks and to interchange between different poles.
You do have to be careful with the carbon fibre modular ones though, because as rigid as they are in use, the walls of the poles are incredibly thin and can be damaged or crushed if you don't take care.
End stops or bump stops are a must, withthe Gardiner poles these are part of the package, can't comment on the Brodex one I'm afraid
The sections are not to long either, so even for a shortarse like me it is a simple matter to assemble and dismantle while the pole is up in the air, though if you have the room, it is so light that lying it flat and doing it on the floor is also quick and easy too.
Can't wait to get to work tomorrow and test it out some more!
