Cleaner parasite (6)

Ross

I believe the answer is:

sponge

I believe this is a double definition.

'cleaner' is the first definition.

'parasite' is the second definition.
(term for someone getting something from others)

(Other definitions for sponge that I've seen before include "Cadge; type of cake" , "Ask for money" , "Light cake; sea creature" , "drunkard or > hanger-on" , "Absorbing" .)

I've seen this clue in The Times.
