Good shots of a middle-aged woman hanging washing on an outdoor line on a cloudy day. She looks quite harassed.
Cut to a younger woman putting clothing and linen on the rods of a new rotary dryer. She switches the machine on (looks like a top loading tumble dryer) and we see the washing moving around on the rods through the window.
The woman goes off to use her rotary ironer - like a sort of heated electric mangle that you feed clothes through so they come out pressed the other side.
The woman then starts to unload her dryer.
Note: documentation on file includes leaflets on Oprim Drying Machine and Ironer - "Hooray! finished ironing and time to spare".
