Swiffer product (3)
I believe the answer is:
mop
'swiffer product' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mop that I've seen before include "Finish off a task - . . . up" , "Swab" , "Clean; mass of hair" , "Instrument for cleaning" , "A thick mass of hair on head" .)
