No. Most robots rely on the filter system of the pool, for "power"
and filtering. Those equipped with "filters" aren't going to filter
very fine particulate.

What is
considered the best model these days as a filter system replacement?

Whatever worked in the past, usually.

I looked at an *old* pool that was @25x50x10' with a real "deep end".
The "pump house" was a good 100' distant.

As I think I understand it, the height of the pump relative to the
waterline and outlets are of consideration.
