In many hotels, housekeeping is responsible for pre cleaning function rooms and other public areas as outlined in the catering department's instructions or in the convention service department's directives. Housekeeping also is involved with cleaning up after functions. Housekeeping must be appraised of special function well in advance so that the necessary work can be scheduled and carried out properly. Function rooms must be cleaned in plenty of time to avoid any embarrassing situations.for example, you do not want last-minute furniture moving going on as guests are arriving.function rooms need to be turn down and clean immediately after guest depart.if you wait too long to do this stains have time to set in upholstery or carpets and vermin will be attracted to the debris.
