the bigger A frame ladders were used in commercial with high door entrances etc but now in commercial due to health and safety everything is done with poles etc.
The small A frame ladders are used in domestic when 2 people are working together, 8ft being an inbetween size for everything and adaptable for 6ft heights without buying too many ladders.The A frame is placed in the corner of the frame leaving the window accessable for cleaning, their is no chance of ladder slipping over the glass as the ladder gets jammed with the weight of standing on it.
when working yourself on domestic you just use 1 big ladder and adapt when needed/I carry a small 2 ft extention pole on a holster and when I come to windows i use the pole to reach areas I can not reach, I pole to about half way then finish of with normal sweeguee
equipment carried
unger belt with harness, you need to take this and get it aitered to fit correctly
on the belt is 2 pockets for scrims 1bucket on belt 16 inch sweegee and 14 inch winwash in bucket on a belt , 2 holsters 1 for 2ft pole 1 for 22 inch sweegee for conservatories if needed.sounds a lot but it is quite light
window cleaning is all about keeping the flow going to get the numbers
like driving coordination without thinking -- it increases reactions, relating to increasing earnings. with step ladders you start - stop to change ladders
also carrying an additional set of ladders= time of clean drops dratically
its the same with wfp thinking the job out before you approach speeds time safety and earnings
hope this helps
