Overview
A cleaner, often called a janitor or custodian, is a person employed to remove waste and to clean, maintain and sometimes repair buildings and equipment. Cleaners work in many environments — offices, schools, hospitals, factories, and public spaces — and their work keeps facilities hygienic, functional, and safe for occupants.
Core duties and typical tasks
Day-to-day responsibilities vary by assignment but commonly include trash collection, surface cleaning, and basic maintenance. Tasks may be divided informally into light and heavy duties: light duties cover dusting, polishing, and tidying of furniture and fixtures; heavy duties involve moving furniture or containers, operating industrial floor machines, and lifting larger waste items.
- Routine cleaning: dusting surfaces, washing floors, waxing floors, and polishing fixtures.
- Equipment use: running a vacuum cleaner or floor buffer and maintaining cleaning tools.
- Sanitation: cleaning kitchens, bathrooms, and common areas to control germs and odors.
Specializations and work settings
Cleaners often specialize by setting or technique. Window cleaners focus on glass and façades, carpet technicians treat and maintain carpets, and some teams train specifically for health-care environments such as hospitals, where infection control is paramount. Other specializations address industrial hygiene in food processing or heavy-duty post-construction cleaning.
- Public spaces: stairwells, hallways, sidewalks, and lobbies.
- Vertical transport: elevators and escalators.
- Facilities maintenance: coordinating with plumbers and carpenters when repairs are needed.
Equipment, techniques and health considerations
Modern cleaning uses a mix of manual tools and powered machines: mops, scrubbers, buffers, and mechanical extractors. Knowledge of safe chemical handling, correct dilution, and appropriate personal protective equipment (gloves, goggles, masks) reduces health risks. Regular maintenance of equipment and clear labeling of cleaning agents help prevent accidents and product misuse.
Safety, security and professional responsibilities
Beyond cleanliness, cleaners contribute to safety and security. They remove hazards such as broken glass or spills, check handrails and mats, and ensure exits remain clear. Cleaners are often the first to notice issues like vandalism, signs of theft, blocked fire escape routes, or malfunctioning fire alarms, and should report these to supervisors or security staff. Good custodial practice includes prompt hazard removal and timely reporting so specialists can address repairs or security incidents.
History and societal role
The English word "janitor" derives from a Latin term for doorkeeper; historically, custodial roles combined cleaning with simple building oversight. Over time the occupation professionalized: training, safety standards, and specialized equipment have expanded the scope and complexity of the work. Cleaners provide essential services that support public health, business continuity, and the appearance of institutions.
Notable distinctions
Cleaners should not be conflated with specialist tradespeople: while custodians may perform minor repairs or identify maintenance needs, major plumbing, electrical, or structural repair is carried out by licensed professionals. Similarly, infection-control cleaning in medical facilities follows stricter protocols than routine commercial cleaning and typically requires specific training.
