Some hoover, all sweaty, in dungarees (8)
I believe the answer is:
overalls
'dungarees' is the definition.
(thesaurus)
'some hoover all sweaty' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'OVERALLS' is hidden within 'hoover all sweaty'.
'in' is the link.
(Other definitions for overalls that I've seen before include "Save roll (anag.)" , "Dungarees" , "Protective wear" , "Protective garment" , "Boiler suit" .)
