I'll use a pool cleaning robot instead to suck up leaves and dirt that fall

keep up with keeping the pool clean without excessive maintenance?

No. Most robots rely on the filter system of the pool, for "power"
and filtering.

No they do not. The simple pool cleaners use either suction or pressure,
via a hose and the pool's pump (or an auxiliary pump for some) but the
robots do not have any plumbing. The robots are powered by a DC power
source via a cable.

The robots do a much better job of cleaning, especially for sand and
dirt. When I had a Polaris cleaner it picked up leaves just fine, but
finer pieces of debris like sand when right through the collection bag.
