This manual is for the still very common Turbopower U1220.

 This manual is for the Hard Body Total System Plus cleaners. I still have my U2604, although it's very faded now sadly.

 AA later style manual for the Hoover 262

 Original manual for a Hoover Hooverette 2944b

 I used to have the cleaner that went with this manual, both long since gone. This U4003, along with an orange Constellation and Celebrity came over from America to cover strike action at the UK factories, hence the totally different style to UK cleaner manuals of the era

This vintage manual is from a Hoover Junior 375 that I used to own.
