This keeps the bedding much much drier. I spot pick poops and the bedding right around it. The only unpleasant smell is right after someone makes an eye-burner, which is not often. This watering station is used by ten ducks.
I clean and refill the pot once a day (this is for their overnight shelter). I scrape the poopy top off the sawdust once a day, and refill sawdust as needed. Takes maybe five minutes a day.
