"Anasafisha dirisha lake la chumba."

Translation: He cleans his room window.

I wrote "He cleans his bedroom window" but it was marked as incorrect. Is that too specific a room? Since the room is his or hers, I thought it was implied that it was the bedroom.

Bedrooms are the rooms in a house usually designated by individual possession so it's a likely response.

"He / She cleans the window to his / her room." "To" is employable here because it denotes the specific location of the window. Example: The key to his door.
