Cleaner falling over, oops! -- carrying something from the butcher's (7)
I believe the answer is:
shampoo
'cleaner' is the definition.
(shampoo is a kind of cleaner)
'falling over oops carrying something from the butcher's' is the wordplay.
'falling over' says the letters should be written backwards (letters falling back).
'carrying' means one lot of letters goes inside another.
'something from the butcher's' becomes 'ham' (meat product).
'oops' back-to-front is 'spoo'.
'spoo' enclosing 'ham' is 'SHAMPOO'.
(Other definitions for shampoo that I've seen before include "detergent" , "Washing preparation (from Hindi)" , "Hotel freebie - Warren Beatty movie" , "clean" , "hairdressing" .)
