A robot cleans the deeper portion of a beach-entry pool well, but the ultra-shallow "beach" itself — where water tapers to zero — is too shallow for a robot to stay submerged and grip. Expect the robot to handle the main pool and to give the shallow entry a quick manual brush.
How beach entries challenge robots
A zero-entry pool slopes gradually from deck level into the water. Where the water is only an inch or two deep, a robot can’t stay submerged, keep suction, or maintain traction — so it can’t effectively clean that strip. It’s the same limitation as a very shallow tanning ledge.
What the robot does well
Once the water is deep enough (roughly 6+ inches), a strong-climbing, well-navigating robot like the Dolphin Sigma cleans the floor and walls thoroughly and can work partway up the slope where depth allows.
A practical cleaning plan
- Let the robot cover the main pool floor and walls.
- Give the shallow beach a quick brush-and-skim by hand — a minute of effort.
- Choose the robot based on the deep-end size and your debris type.
