A low cost way to keep a flat above-ground pool floor clean without a booster pump or charging. It does not climb walls, has no timer, and its short cycle means big jobs need restarts. Buy it for floor debris in a small above-ground pool, not for walls or silt.

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.

What reviewers found

Dolphin E10

  • Poolbots (retailer review): In their test it cleaned floors reasonably well with an easy basket, but it does not clean walls or the waterline, has no scheduler, tangles easily, and let silt and sand cloud the water. Source

Dolphin (Maytronics) Sigma

  • The Pool Nerd: Ranked it the best robot the site has tested; the center brush rolled over the main drain every time in weeks of daily testing and its waterline cleaning was the strongest of any Dolphin tried. Affiliate site with links to Dolphin dealers. Source
