Hi
This may be a silly suggestion. Have you been to your local council recycling centre. In my local centre there are separate accessible storage areas for small electricals. The last time I visited it was full of vacuums of all varieties. If you don't fancy taking a chance visiting the centre, contact your local council recycling officer and find out what they do with the unwanted electricals. I think they sell them on to companies, who take them apart and recycle any usable parts. Or keep looking in local junk or charity shops, one will turn up eventually.
