As a night shift cleaner, you work after-hours in an office building or similar facility to maintain the cleanliness of a business, organization, or multi-tenant commercial property. Your duties include taking out the trash, cleaning the floors, and wiping down furniture. Your responsibilities might also include cleaning bathrooms, desks, and taking care of spills. As a cleaner, you can either work directly for the business or property owner or for an outside cleaning company. Retail spaces, offices, and restaurants all offer night shift cleaning positions. You must also report safety hazards, mix chemicals, and identify any malfunctioning equipment.
