Idiot returning has funny scrubbers (7)

Ross

I believe the answer is:

loofahs

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

'scrubbers' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.

'idiot returning has funny' is the wordplay.
'idiot' becomes 'fool' (I've seen this before).
'returning' says the letters should be written backwards.
'funny' is an anagram indicator.
'fool' reversed gives 'loof'.
'has' with letters rearranged gives 'ahs'.
'loof'+'ahs'='LOOFAHS'

Can you help me to learn more?

(Other definitions for loofahs that I've seen before include "Back scratchers" , "Dried part of a plant used as washing sponges" , "Bath sponges" , "Has fool got the back brushes?" .)
