Which robot pool cleaner is best for a large pool
Top pick
Polaris 9650iQ Sport
For large, debris-heavy in-ground pools, the Polaris 9650iQ Sport brings together a 70-foot cable, a five-liter canister, 4WD and full-zone modes.
Why it suits this job
- Cable length or battery life to cover the whole area
- Reaching walls and corners through its navigation
- The catch

- Go with Dolphin Nautilus CC Supreme if
- An in-ground 50-foot pool that needs full-line scrubbing and finer filtration
More reasons we picked it
- A big basket so you stop less often
- Help getting a bigger body out of the water
