This really is a great topic! I'm 99% commercial and would be happy to post vac for an extra charge. Most property management already have a janitorial company in charge of vacuuming so no point in charging the customer for a service they are already paying for. But then the question becomes what exactly is the janitorial doing when they vacuum? If improper process, shortcuts etc. are happening it can hurt. In my experience allot (not all) janitorial do a pretty poor job with improper vacs or shortcuts. The most popular method is the "lone back pack vac with a wand attachment". If you blink you missed them vacuuming.
If you have a maintenance contract for instance and are cleaning the carpet on monthly basis you will know pretty quick if proper vacuuming methods are being used by what you as a cleaner can pull out of the carpet. I cannot express how important a proper vacuuming frequency and equipment is to you as carpet cleaner especially if you are on a maintenance contract. With that being said it raises allot of questions when left in the hands of another service that the customer is paying for. You can educate the customer and other service,,, but that can lead into blame and finger pointing unfortunately.
