'cleans house' is the definition.
'hoovers' can be an answer for 'cleans' (hoovering is a kind of cleaning). I'm unsure of the 'house' bit.

'starts to help out about sunday' is the wordplay.
'starts to' indicates taking the first letters.
'about' becomes 'over' (both can mean around).
'sunday' becomes 's'.
The first letters of 'help out' is 'ho'.
