He clears the way for us (4,7)

I believe the answer is:

road sweeper

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

'he clears' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'way for us' is the wordplay.
'way' becomes 'road' (road is a kind of way).
'for us' becomes 'sweeper' (I can't justify this - if you can you should give a lot more credence to this answer).
'road'+'sweeper'='ROAD SWEEPER'

'the' acts as a link.

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
