The biggest difference between janitorial and commercial cleaning services is that commercial services have the training and equipment to take on larger tasks and projects. These jobs don't need to be done on a regular basis but when they do, a janitorial service won't quite cut it.

What is the difference between a janitor and a cleaner? The job of a cleaner is purely to clean a designated area while a janitor's job also includes maintenance. Cleaners often work in small buildings or residential areas, while janitors work in larger or public spaces.

The difference between janitor and custodian positions is that a custodian's job is more consistent and overarching than that of a janitor. While a janitor reports for shift work at a specific time to clean designated areas, a custodian's job description entails the general upkeep of a property or facility.
