I'd be inclined to agree with Graham here
These systems are a 'must have' for any window cleaning company, because with the governments plans to institute a ladder ban, they will soon be the only way to do this work. Very soon this will be the only way to clean windows legally and safely so don't get left behind.
This is simply not true. It'd be fine if the seller was saying its a way to work more safely, but when people come out with things like "the government plans to institute a ladder ban" it really gets my goat. This is simply a lie to try to sell something.
I might email him and ask where it says this in the proposal document, because having studied all of the 166 pages, I did not see that anywhere.
