SCORED
The pick for in-ground owners who want the most automated corded Dolphin: app control, a weekly timer and strong waterline scrubbing with no battery to wear out. It is the most expensive robot on this list and does not skim the surface. Skip it if you do not need the app; the Premier cleans similarly for less.
Best for: set and forget in-ground pools. Skip if: you do not care about app control.

Questions buyers ask

Can it run on a schedule without me?
