Sweetheart surrounded by cleaning equipment sulks (5)

Ross

I believe the answer is:

mopes

'sulks' is the definition.
(thesaurus)

'sweetheart surrounded by cleaning equipment' is the wordplay.
'sweetheart' becomes 'e' (the heart/centre of 'sweet').
'surrounded by' indicates putting letters inside.
'cleaning equipment' becomes 'mops'.
'e' placed within 'mops' is 'MOPES'.

(Other definitions for mopes that I've seen before include "is miserable" , "Hangs around apathetically" , "Feels dejected" , "Moons around" , "Broods about poems" .)

I've seen this clue in The Telegraph.
