Pool fit and cleaning reach

Aquabot X4 has a published maximum pool length of 60 ft; the other model does not have a verified length in our source material.

Filtration and debris
Aquabot X4 has documented included filtration—Basket—while the other model's included media is not fully published. Aquabot X4 also has the better documented path for bulky leaves and larger debris.
Controls and day-to-day ownership
