Cleaner making loud noise? That's about right (5)
I believe the answer is:
broom
'cleaner' is the definition.
(I've seen this before)
'loud noise? that's about right' is the wordplay.
'loud noise?' becomes 'boom' (I've seen this in another clue).
'that's about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'boom' placed around 'r' is 'BROOM'.
'making' acts as a link.
(Other definitions for broom that I've seen before include "Sweeper (said twice for a car!)" , "Plant - sweeper" , "one's often fitted in a cupboard" , "Yellow-flowered shrub" , "A new - - sweeps clean" .)
