## What reviewers found

### 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.

### MOVA Rover X10

- Bob Vila (4.7/5): Upgrade Pick in its tested roundup. Performed well on fine dirt, algae and floating debris, with strong battery life and thorough edge cleaning; called the underwater relay one of the most innovative features it tested. One of the heaviest robots it tried. Subscores: Ease of Use 4.5/5, Performance 5/5, Value 4.3/5. [Source](https://www.bobvila.com/articles/best-robotic-pool-cleaner/)
- EFTM: A 150 min complete clean covered 300 sq m and used 63% of the battery; floor only took 58 min and 18%. The map loosely matched the pool, no mode cleaned the steps, it never parked at the chosen spot, and three firmware updates arrived in week one.

- Basic Tutorials (84/100): Silver Award. Reliable floor pickup and active waterline and surface cleaning in a 4 x 2 m pool; weaker on narrow steps and corners, LiDAR accuracy dropped in murky water, and buoy range was about 15 m. Subscores: cleaning 90, features 92, app 75. [Source](https://basic-tutorials.com/reviews/gadget-reviews/mova-rover-x10-review/)
