Hi Andy - welcome to the forum - there are a few threads about this already on the forum - the concensus seems to be that they probably wouldn't work that well- if I had one on now it would probalby be beeping and flashing wildly - I have just finished vacuuming the stairs and I am in a lather of sweat and feeling hot :lol: :lol: - but I am definitley not in hypo territory! - but I am sure for some they may be useful
