washing machine

I'm a little stuck... Click here to teach me more about this clue!

'be cleaner' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'man wishing each woolly' is the wordplay.
'man wishing each' can be anagrammed to 'WASHING MACHINE'.
Though, I am not sure how this is indicated.

'could' is the link.

Can you help me to learn more?
