A self-service kiosk enables customers to conduct rental transactions for carpet cleaning machines without the need of assistance from store personnel. The kiosk comprises a housing having several stalls or bays that hold and display carpet cleaning machines and carpet cleaning accessories for rental. The kiosk controls whether such carpet cleaning machines and carpet cleaning accessories can be removed from or returned to the kiosk. The kiosk also optionally includes a control panel for conducting a rental transaction. The self-service kiosk may also include automatic dispensing of cleaning products purchased by the customer at the kiosk. Still further, the self-serve kiosk may include shelving for holding cleaning products that can be purchased separately at a checkout counter.
