Do I need to go out to stay in a hotel for cleaning?

You don't need to go out in this situation.

Usually you don't need to clean yourself when staying in a hotel. The hotel will have special staff to clean and tidy the room. If you need to keep your room clean during your stay, you can put the garbage in the trash can and send the laundry to the hotel laundry room or service desk. If you need to change towels, sheets and other items, you can contact the room service staff of the hotel, and someone will come and handle it.
