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.

Janitorial service often refers to the use of a cleaning service for businesses rather than just residential. All rooms are fully furnished and residents reside in single, double, or triple rooms and use shared common bathrooms cleaned daily by janitorial staff.
