Mrs Mop as tea woman (8)

I believe the answer is:

charlady

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

'mrs mop' is the definition.
The definition suggests a singular noun which matches the answer.

'tea woman' is the wordplay.
'tea' becomes 'char' (I've seen this before).
'woman' becomes 'lady' (lady is a kind of woman).
'char'+'lady'='CHARLADY'

'as' acts as a link.

Can you help me to learn more?

(Another definition for charlady that I've seen is " Female cleaner".)
