It's been on the news about this all day and there's been further info just posted on their website which says this;

7 - the cleaning of windows by hosepipe, sprinkler or other similar apparatus which is connected directly to the mains supply;

Does this mean WFP can be used because at the time it's not connected directly to mains?
