Where everybody goes in to sweep around the floor (8)

I believe the answer is:

ballroom

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

'the floor' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'where everybody goes in to sweep' is the wordplay.
I cannot really see how this works, but
'everybody' could be 'all' (all people) and 'all' is present in the answer.
'sweep' could be 'broom' (synonyms) and 'broom' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'around' acts as a link.

Can you help me to learn more?
