I use a Harris pole with Wagtail on for windows over conservatory, then take the Wagtail off and detail with a m/f cloth held on with elastic bands that I keep round the end of the pole so they're handy. The change the cloth to wipe the sill.
BUT, I'd never do other windows with a trad pole, you just can't detail properly and you're not close enough to see the job.
For me it's trad/ladders or switch to wfp.
