## 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](https://www.poolbots.com/learn/dolphin-e10-review)

### 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.
