It is possible to dramatically reduce littering. Singapore has strict littering punishments. You don’t see a lot of litter on the ground. Of course caning people for littering isn’t a very popular policy in most countries. But in Singapore they also pay people to sweep the streets, because despite the laws, trash still will accumulate. Note that Singapore also doesn’t have a minimum wage which means people can be paid a low amount to clean the streets. In the U.S. we don’t enforce littering laws, and we also mostly don’t pay people to sweep streets. So we have very dirty streets. What a robot can do is work for very low cost to clean up streets. Far below minimum wage.
