Can the hotel model room not check the mechanical and electrical equipment?

You can't. Hotel model rooms should be checked for electromechanical, because electromechanical plays a great role in hotel operation, and electromechanical problems will lead to hotel closure. Hotels are also called hotels, hotels, inns, guest houses, business trips, inns and inns. China is a hotel, guesthouse, etc. While Malaysians and Singaporeans are hotels.
