Sweeper's light touch (5)

Ross

I believe the answer is:

I believe this is a double definition.

'sweeper's' is the first definition.
(something which sweeps)

'light touch' is the second definition.
(synonyms)

(Other definitions for brush that I've seen before include "Tool for cleaning or painting", "Sweeping implement", "Slight touch; fox's tail", "Cleaning implement", "Sweep".)

I've seen this clue in The Guardian.
