Janitors typically do the following:

• Gather and empty trash and trash bins
• Clean building floors by sweeping, mopping, or vacuuming them
• Clean bathrooms and stock them with soap, toilet paper, and other supplies
• Keep buildings secure by locking doors
• Clean spills and other hazards using sponges and squeegees
• Wash windows, walls, and glass
• Order cleaning supplies
• Make minor repairs to the building, such as changing light bulbs
• Notify managers when the building needs major repairs.

Janitors keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some do only cleaning, while others have a wide range of duties. In addition to keeping the inside of buildings clean and orderly, some janitors work outdoors, mowing lawns, sweeping walkways, or shoveling snow. Some janitors also monitor the heating and cooling system, ensuring that it functions properly.

Janitors use many tools and equipment. Simple cleaning tools may include mops, brooms, rakes, and shovels. Other tools may include snow blowers and floor buffers. Some janitors may be responsible for repairing small problems with electricity or plumbing, such as leaky faucets.
