ご質問ありがとうございます。
まず、keep「〜の状態にしておく」 を使って表現すると
You should keep your room clean enough to invite your friends at any time.
「あなたは、いつでも友人を呼べるくらいに部屋を綺麗にしておくべきだよ」
また、tidy up「片付ける」を使って
You should tidy up your room so that you can invite your friends over anytime.
「あなたはいつでも友人を呼べるように、部屋を綺麗にしておくべきだよ」
などと表現することができます。
ご参考になれば幸いです。
