Space for cleaner to take top off (4)
I believe the answer is:
room
'space' is the definition.
(room is a kind of space)
'cleaner to take top off' is the wordplay.
'cleaner' becomes 'broom' (I've seen this before).
'to take top off' means to remove the first letter (I've seen 'taking top off' mean this).
'broom' with its initial letter taken off is 'ROOM'.
'for' is the link.
(Other definitions for room that I've seen before include "Place" , "bedsit?" , "Latitude" , "Space (for elbows?)" , "Chamber; scope" .)
