There are of course all the usual trad methods, on internal stuff you are going to have to use some form of trad method.
I went up to the cleaning show at the NEC and saw an incredibly expensive way of using extension poles, pads and a battery powered pure water sprayer, harnessed on a belt around your waist and fed up some light hose just as in external WFP.
Very minimal water used, little different to misting with a hand sprayer and buffing with a cloth (microfibre or scrim).
Didn't matter if the glass was left damp, so long as you had cleaned the glass, due to the pure water it dried out fine.....cost?......................close on a grand, and all you got with that was a five ft pole! (£100 per extra extension(or thereabouts))
A good looking system, but incredibly expensive.
Now for myself I've often used a proprietary window cleaning spray, misted and buffed clean and dry with a - now - microfibre cloth, and that works absolutely fine, oh, and for large panes I'd simply use an applicator and squeegee (horses for courses and all that).
But as a result of seeing this system in action I decided to try out nothing more than pure water in a prayer and using a very clean cloth.
Worked just fine and the glass would dry out spotless even when left damp, providing you had of course cleaned the glass! And keeping the cloth or scrim very clean too, so it does mean going though more cloths than normal.
Back in the depths of winter I bought 25 litres of isopropanol to try and stop my hoses and brushes from freezing up, got plenty left, so I have started putting it into the sprayer, diluting it down about 20:1 (I think!)
Now using that has REALLY made a difference!!
Glass can be left damp and it is way fast!
Today I did one of my weekly jobs, a pub inside and out, also do a load of their mirrors and I would use a combination of spray & buff and applicator and squeegee where required.
But this time I used only the new spray and a very clean microfibre cloth and cut over 10 minutes off the time taken to do the job.
Normal window cleaning spray - such as Mr Muscle and so on - have dyes and other additives, you leave the glass damp and you will leave smears behind.
Isopropanol is as pure as the water we use, so mixed with pure water you can leave glass damp without fear of smears, plus the ISP helps cut through greasy marks and so on.
I have been amazed at how effective it is, you still need to know what you are doing of course, but it works, and it is the same principle as the expensive Dutch system.
Wouldn't be a big stretch of ingenuity to add a pump up sprayer, a changeable pad on an extension and away you go with a DIY system of the Dutch one.
I've got a Dr's surgery to do Tomorrow, in and out...usually squeegee all the inside stuff as the panes are very straight forward and takes me about 20 minutes, so I'm going to try it with the new spray and see if the time taken (and quality of course) is any faster than with a squeegee...oh, and I am no slouch with a squeegee, have done this place for over 20 years, so I'm VERY quick at it now...
Will be interesting to see if I'm any quicker
