dustpan

I'm a little stuck... Click here to teach me more about this clue!

'cleaning implement' is the definition.
'dustpan' can be an answer for 'cleaning' (thesaurus). I'm unsure of the 'implement' bit.

'stand up floppy' is the wordplay.
'floppy' indicates an anagram.
'stand'+'up'='standup'
'standup' anagrammed gives 'DUSTPAN'.

Can you help me to learn more?

(Other definitions for dustpan that I've seen before include "Stand up (anag) - receptacle for collecting particles" , "Container associated with brush" , "Receptacle for sweepings" , "Item of floor cleaning equipment" , "Sweeper's receptacle" .)
