Abandoning backwoods, I'm often out on the tiles (9,5)
I believe the answer is:
scrubbing brush
'i'm often out on the tiles' is the definition.
'abandoning backwoods' is the wordplay.
'abandoning' becomes 'scrubbing'.
'backwoods' becomes 'brush' (I can't justify this - if you can you should believe this answer much more).
'scrubbing'+'brush'='SCRUBBING-BRUSH'
(Other definitions for scrubbing brush that I've seen before include "It's used to clean" , "Stiff domestic cleaning implement" , "One's employed to scour" , "Cleaner" .)
