Cleaner range kept by nameless woodworker (6,7)
I believe the answer is:
Here is my best explanation:
'cleaner' is the definition.
'range kept by nameless woodworker' is the subsidiary indication.
I cannot quite see how this works, but
'range' could be 'sweep' (sweep is a kind of range) and 'sweep' is present in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for carpet sweeper that I've seen before include "Household appliance", "Domestic appliance for picking up dust", "Cleaner", "Floor cleaner", "Domestic cleaning equipment", "cleaning device" and "Cleaning equipment - we respect a rep (anag)".)
