A carbon facelift would be my choice, a very light, rigid & robust pole. the base section of the 24ft'er is only a wee bit thicker than a broom handle too. very easy to use.

As Tony say's, the facelift will probably be the tool for you, particularly as you want the pole hose to be through the pole.
Though they are nothing like as light as the Gardiners Supalite pole.
I've used absolutely nothing else for cleaning all windows with for the last 3 or 4 months...well, since Valentines day anyway
and I'd never go back to any other kind of pole (one should never say never...should one
)
But you do have to be gentle with these poles...
