Spoken to the wise one ahem the gf, shes been over at a friends who has a £99 Vax thing, tested it out and it worked fine enough so likely get one of those once I have got my 2nd system from a friend on here
In the meantime I have just managed to convert a 1970's Vax which only has its shampooing parts into a hoover only system with no bag just empty the bottom intake tank.
Should do me for 4week.
