。
I want you to hurry and tidy up the room.
Literal
Room [object-を] hurrying tidy [want you to-てほしい] [explanatory-の].
Uses ~てほしい to express the speaker's desire for someone else to act. The sentence-final の adds a soft explanatory or assertive tone, often associated with feminine speech. いそいで (急いで) functions as an adverb modifying かたづけて.
