Evaluation of Repeated Cleaning Ability of a Restroom Cleaning System for Scattered Urine

Automation of toilet cleaning is required at retail stores such as convenience stores. In this study, a system to clean the toilet room was proposed. The system consists of a toilet bowl for reducing scattering urine, toilet bowl top surface cleaning mechanism, and toilet floor cleaning robot. The toilet bowl reduces scattering urine due to the shape like a urinal and the lift function. The experiment to evaluate the effect of the toilet bowl top surface cleaning mechanism and toilet floor cleaning robot was conducted. The mechanism and robot cleaned the simulated urine at removal rate over 98 [%], which is a considerably high value. However, it remained as a future task to clean continuously keeping the high removal rate.
