1. A floor cleaning machine comprising:
a cleaning head configured for cleaning a floor surface;
a solution tank configured as a reservoir for a cleaning solution;
a pre-canister sensor configured to receive the cleaning solution from the solution tank and further configured to measure a concentration of any dissolved solids within the cleaning solution, thereby creating a baseline measurement;
a canister assembly configured to receive a first portion of the cleaning solution from the pre-canister sensor and further configured to dissolve portions of a solid chemical form into the first portion of the cleaning solution thereby forming blended droplets, the canister assembly having a spray nozzle positioned vertically above the solid chemical form; and
a post-canister sensor configured to receive a mixture of a second portion of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly, the post-canister sensor configured to measure the concentration of any dissolved solids within the mixture of the second portion of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly;
wherein a comparison of a post-canister measurement from the post-canister sensor and the baseline measurement from the pre-canister sensor outside of a desired range results in replacement of the solid chemical form.
