We still have a Kirby Heritage II here, with the full kit of extras and almost unused since it was bought. It is a great machine, but proved too heavy for my partner to manage and was soon relegated to the under stair's cupboard. It cost a small fortune, too heavy for us now - I really ought to see if I can sell it on, maybe to a collector.
IIRC, they even had a dandruff attachment. For some bizarre reason, they assumed that people would vacuum their head rather than washing their hair.
