It speeds up every clean by about 30 seconds. At about 25 cleans a day in summer (two of us) that's 12/13 mins saved a day, which takes us halfway to doing one more clean a day (or spending another quarter of an hour at home).
We're also noticeably less knackered at the end of a day. Me, at 48, you might understand, but my Joey (19 on Friday) also feels less tired.
But you could be right; keeping the job slower and harder than it has to be might be the way forward.
As for
who holds your pole for you whilst your cleaning, surely you don't its far too heavey!
the antidote to your sarcasm is to ask you in return, why don't you tie a brick to the end of your pole, surely it's too light?
