Pool cleaner choice for a Denver backyard in a dry, dusty season?

We have a small backyard pool here in Denver, and between the dust that blows in and the pollen in spring, the floor needs attention almost daily. I have been looking at robotic pool cleaners for 2026 and trying to work out what actually matters for a place like ours, where the water level drops fast in summer and there is a lot of fine grit rather than big leaves. The thing I keep going back and forth on is whether a model with a fine filter is worth it, or whether those clog too quickly and become a weekly cleaning chore of their own. I also worry about how these units handle a pool that is not perfectly level, since our setup is older. I have only read third-party information online, so I would rather hear from people actually running one through a Colorado season. What has worked for you, and what would you avoid?
