Automatically get a rug (3)
I believe the answer is:
mat
'a rug' is the definition.
(both are floor coverings)
'automatically get' is the wordplay.
'get' says the answer is hidden in the clue (I've seen 'got' mean this).
'MAT' is hidden in the letters of 'automatically'.
(Other definitions for mat that I've seen before include "To wipe your feet on" , "Tangle" , "Rug; without a shine" , "Small carpet" , "Floor-pad" .)
