Floor-washing implement (3)
I believe the answer is:
mop
'floor-washing implement' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mop that I've seen before include "Swab" , "Polish" , "Finish off a task - . . . up" , "Tangle of hair" , "Bundle of soft material at end of stick for cleaning" .)
