Clean hotel over and over (6)
I believe the answer is:
hoover
'clean' is the definition.
(hoovering is a kind of cleaning)
'hotel over and over' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet).
'over' becomes 'o' (cricket abbreviation).
'and' means one lot of letters go next to another.
'h'+'o'+'over'='HOOVER'
(Other definitions for hoover that I've seen before include "J Edgar . . . . . . was FBI chief" , "Vacuum cleaner of the old American president" , "Clean with vacuum cleaner" , "Type of 5 down" , "US president in House throughout" .)
