No offense, but I don't like it.
The narrator sounds patronising. The images that get drawn mostly don't relate to window cleaning, but seem to be generic ones taken from a library (eg the man with the briefcase and his arms in the air, big buildings)
And what's all this "3 steps" business. Doesn't make any sense. If I was told that in order to hire a window cleaner it would be "a three step process" I'd think, no thanks. It seems like that's something that's been put in because you could find doodle video of a 3-step process and thought you could somehow fit that into the video. Silly if you ask me.
Just my opinion, but it would not persuade me to go for your service. In fact it would have the opposite effect.
