Shower cleaning tool (Taverham NR8)

Not sure what this is called but it was my late Mums and came from the Easy Life magazine. It is used to clean tiles inside shower compartments and and bathrooms and is adjustable. Needs some sort of cleaning pad on the rectangular head which are available from Easy Life or of course one could make up their own. Thought I'd offer it just in case, otherwise will take to the tip.
