What cleaner needs to baffle the clergy? (10)

I believe the answer is:

floorcloth

'what cleaner needs' is the definition.
(a cleaner might clean with a floorcloth)

'baffle the clergy?' is the wordplay.
'baffle' becomes 'floor' (floor can mean to amaze or baffle).
'the clergy?' becomes 'cloth' (I have seen 'The clergy ' mean 'cloth' so perhaps 'clergy' could also mean 'cloth').
'floor'+'cloth'='FLOORCLOTH'

'to' acts as a link.

(Another definition for floorcloth that I've seen is " cleaner?".)

I've seen this clue in The Telegraph.
