Clean compass (5)
I believe the answer is:
sweep
This clue is a double definition.
'clean' is the first definition.
(sweeping is a kind of cleaning)
'compass' is the second definition.
(sweep is a kind of compass)
(Other definitions for sweep that I've seen before include "Row" , "Expanse" , "a puppet" , "pass swiftly" , "Wield a broom" .)
