"but Numatic Henry, especiallu commerical version, were the way to go"
They still are mate (says a recently retired cleaner)
I despaired when they retired the henry at my last job because there was a Vax on "special offer" - it was clearly shite.
Henry's are bomb proof, the spares and bags are cheap and readily available and it's made in Britain - a success story no one knows about...
