I am $2.00 for 4 min. My competitor is .75 cents. I clean and wipe down my vacs daily. Clean inside every two week, more on busy time of year and shake down vac bags. I go through vac motors every 5 to 6 years some time longer. People are willing to pay more if your equipment is clean and works. When I have a problem I always refund money no questions asked, this is something my competitors do not do freely and my customers tell me this.
On another note: I have cameras and if someone uses my trash for house trash I post a PIC of them on front of wash and in time someone turns them in or the person that did it calls. I love it when an X calls and says this use to be my girlfriend or boyfriend. One time a guy called and turned in his own brother. Hahaha
