The present invention is a programmable dispensor for dispensing the appropriate amount of cleansing agents during peak period and adequate amount of cleansing agents during off-peak period without comprising the overall bacteria kill rate. The dispensor features a microcontroller coupled toa solenoid valve for allowing users to program the dispensing of cleansing agents over a predetermined number of peak-hour intervals and at least one cut-off period. The dispensor of the present invention also incorporates a float subassembly within a bucket for receiving measured amounts of cleansing agents and accomplishing two important functions in response to the actual usage of urinal: (1) dosing the urinal upon demand when the urinal is flushed, and (2) dosing the urinal directly when the urinal is either not flushed or flushed infrequently. Dosing on demand is carried out when a portion of the flushed liquid from the flush pipe is diverted to the bucket overa connecting pipe and an elbow channel. A float compartment of the float subassembly topples the subassemby which is pivoted over a hinge in the bucket. The cleansing agents mixes with the flush liquid before returning to the flush pipe. Direct dosing results from the overflow of cleansing agents from a tongue portion of the float subassembly through the elbow channel and connecting pipe into a discharge tube within the flush pipe. As such, a given supply of cleansing agents is guranteed to meet the pattern of actual urinal usage without comprising the overall bacteria kill rate in urinals.
