Mud-Free Existence?

A world without mud would be far more enjoyable than the current one, in my opinion. There must be a way to separate rain from dirt. There must! After all, you've separated the sea from the mountains, and the downtrodden from prosperity. Why not confine rain to bodies of water and foliage, which can fully absorb moisture?

In a mud-free existence, one would not have to wipe it off one's shoes or one's dog before entering one's home. This would translate directly into more free time to worship you, honor you, obey you, etc. -- each in our own way. We could spend more time helping the downtrodden, for starters. And the downtrodden could think of more effective ways to improve their situation. There are lots of good things we can do instead of removing mud from our lives. Might you give this some consideration for the new, improved world to come?
