Need a pool robot for the community pool (better offers long battery life and powerful)

Hi everyone, I'm currently in charge of a community swimming pool. As the weather gets warmer, more people are coming here, which means more frequent cleaning work. Therefore, we want to move towards a smarter solution to avoid the rising costs of manual cleaning services. Finally, the homeowners' association and we raised around $600, which we want to use to purchase a robot cleaner that could meet our pool's cleaning needs.

Here are the pool specifications:

Length: Approx. 98 feet | Width: Approx. 18 feet

Deep End Depth: 5.6 feet | Shallow End Depth: 3.4 feet

Shallow to deep section volume ratio: around 3:1

Besides handling floating debris and surfaces well, we also want it to finish the pool in one go without running out of power.

Since this is our first purchase, and none of us really knows much about this kind of product, we'd really love to hear your thoughts. Any related options are appreciated
