Okay, bit of a stretch here, way back last year about October their was a thread about wfp video's ( well a discussion about them ) someone posted a video of them or a window cleaner water fed pole cleaning a large detached house in around 3.5 to 4 minutes. (The front)
I'm interested in showing this to a staff member, not because it was cleaned really well, but shows how to be purposeful and efficient at a property, it's also easier than me demonstrating it !!
So those with good brains - make my day and find the thread or link
