Hoover Vacuum Cleaner (CT6)

This was my nans and should work fine, but it's sat gathering dust as you can see.
I've only just found the instruction booklet.
I can't guarantee you'll get it to work properly, but I can't see her having one that didn't work.
I was going to take it to the tip, but it would be a shame not to see if it might do someone a turn. Thanks.
