Cleaner, one searching energetically (7)

I believe the answer is:

scourer

This clue is a double definition.

'cleaner' is the first definition.
(scourer is a kind of cleaner)

'one searching energetically' is the second definition.
(somebody scouring in search of something)

(Other definitions for scourer that I've seen before include "Kitchen scrubber" , "Pan cleaner" , "one cleans up" , "Abrasive cleaning pad" , "One searching" .)

I've seen this clue in The Times.
