Yeah yeah yeah. " I could make a video, but don't have time/can't be bothered/why would I..... etc"
All the harsh critics will never make a video themselves as it will either show how poor of a job they would have to do to make those times viable, or actually that they are telling porkie pies.
On a house that size I would expect it take about 15 minutes or just under. But some of you say you could do it in less than 5?
Seeing is believing.
The video I'm going to link isn't a video that was created to show technique but rather a clamp less pole, so the technique shouldn't be criticised. but having said that, it's the fastest WFP window cleaning I can find on youtube, so is a good example fit for purpose.
It takes MR foggy 2 and a half minutes to clean the front of this house. And there is less windows on this house than the OP's video.
So to put that into perspective you "speed cleaners" would have to clean FASTER than MR foggy is on this video to match your so called times.
No frames are cleaned in this video either, so I stick to my original claims that you cannot do a thorough job while being as fast as some of you all claim.
You can have super speed, or quality as fast as you can. Choices have to be made.
Here's the vid;
