Janitors or cleaning personnel are trained to do a heavier job because they help maintain bigger places, like offices, schools, restaurants, etc. They also have the right set of equipment to better clean the place up.

The janitors enable the building to receive good first impressions. In going to any establishments, people almost always look around the area to observe the facilities. Having to go to that facilities for the first time and having to see good remarks all over the place, gives any customer the idea that the place is really well maintained, and would result to them feeling assured that the establishment provides a clean environment.

It’s hard to maintain cleanliness in any establishment because a lot of people come in and out throughout the day. There is no possible way that the owner or the employees can keep track of whoever makes a mess. And for everything to be carefully maintained, you need staff that are specifically tasked to do the job of cleaning and maintaining everything.
