Most large hotels have a maintenance staff, but after hours or in smaller facilities, the bell service staff may be called on to perform basic maintenance. This may include unclogging toilets, replacing light bulbs, replacing a remote control or room television, or other minor repairs as required. They also should know the basics of cleaning a guestroom, in case housekeeping is short-staffed and needs assistance. Bellboys sometimes help with room service deliveries after hours, and with newspaper or bill deliveries to the rooms early in the morning.
