Cleaner’s short holiday (3)
I believe the answer is:
vac
This clue is a double definition.
'cleaner's' is the first definition.
(I've seen this before)
'short holiday' is the second definition.
(short for vacation)
(Other definitions for vac that I've seen before include "brief holiday" , "Break" , "which helps with housework" , "Holiday; cleaner" , "short holiday" .)
