A night office cleaner vacuums and cleans offices in commercial buildings after normal business hours. As a night office cleaner, you wipe down tables, walls, and counters to ensure they are sanitized. You vacuum carpeted areas, sweep and mop floors, and dust surfaces and ceiling fans. Scrubbing and disinfecting the bathrooms are a primary responsibility for night office cleaners. They also make sure the supplies are stocked in the bathroom and kitchen, including soap, toilet paper, and paper towels. You make sure that the office is clean before the next shift of employees arrives. Depending on the size of the office, you may work independently or with several other night cleaners.
