You decide. Your laundromat investment can be either a full-time or part-time commitment. Many successful laundromat owners choose to keep their current jobs since the business is so flexible. In 2012, 63% of laundromat investors listed their laundromat business as their full-time occupation, while 36% were part-time. Your time commitment also depends on how many employees you wish to hire. Employees add to your overhead costs but allow you to offer additional profit-generating services, such as laundry drop-off. 70% of laundromat business investors employ 0-2 attendants.
