Shaun's right, keep the " drip feed "that window cleaning gives and if you really want to clean carpets try to find someone local to let you have a go.
C/C can be a problem for many and your height could be a disadvantage, although longer wands are available,but you might have to get one from the U S A .
I've been lookng into window cleaning recently, as my son was struggling with c/c at 6' 4", seems more of the flash houses, cars, boats, etc, are owned by window cleaners, than c/c'ers.
