There are so many factors, but assuming it is regular work. a squeegee in the hands of an experienced operator is faster nose-to-glass.
Remove operator experience, and water fed window cleaning becomes more efficient.
Remove ‘nose-to-glass’ such that you need a pole, or ladder, and again, water fed window cleaning becomes more efficient.
Add difficult-to-remove concretions and you need an experienced operator.
Pack-out / Pack-up needs to be taken into consideration as well because it is the time from arriving on site to the time leaving site that needs to be assigned as the cost against the revenue.
Last, but not least is safety of the Operator and the Public. Water Fed Window Cleaning is more difficult in high pedestrian environments, but brilliant before and after peak times.
