Here's how you keep them much cleaner, and much less expensed to maintain:
Set up a charge, a credit card tap lock, that is two bucks to use the toilet. But then only reserve the two bucks, and unreserve it a day later. No actual charge made.
Then, put a simple poster inside that features a face looking forward, and a request "keep our commons clean, we have your credit card info".
The mere screening act of requiring someone nearby to own a credit card will cut vandalism by 95%, and the image of eyes being present will also discourage asocial behaviors. Public restroom, it will get nasty, but the nastiness levels would be far more manageable.

I strongly suspect the reason this bathroom was built was so homeless people would use it instead of going in the street.
