ABSTRACT:
The present invention describes a restroom attendant system. The restroom attendant system utilizes a notification device placed in a restroom. A patron would select a request for service button when the patron recognizes that the restroom needs servicing. The notification device can include a cancel feature as well as indicators to indicate when a request for service is in process and if the restroom is considered cleaned. The notification device would communicate with either a main terminal or a service person. The main terminal can further monitor the time between cleanings and request that a restroom be serviced should the time since the previous servicing exceeds an acceptable time-span. The information can be stored, printed, and uploaded to a central receiving station.
