## What reviewers found

### Beatbot AquaSense X

- Digital Trends: Editors' Choice. A 193 min floor and wall session used 76% of the battery; the station ran six plus cycles with no filter handling and the bag about a quarter full; waterline scum was essentially gone after three cycles. Stair cleaning graded B. [Source](https://www.digitaltrends.com/home/beatbot-aquasense-x-review-the-pool-cleaner-for-those-that-want-to-be-pampered/)
- Bob Vila (4.6/5): Tested for nearly two months in two 30 x 12 ft Florida pools. Floor, wall and waterline cleaning were consistently excellent, but the robot is very heavy and the dock is large and needs a hose. Says many buyers could get 85 to 90% of the performance from a Sora 70. [Source](https://www.bobvila.com/reviews/beatbot-aquasense-x-review/)
- Reviewed: Strong cleaning and an intuitive app, but the reviewer called it hard to recommend at its price; surface cleaning was weaker than Beatbot's skimmers and the heavy robot was a chore to carry. Recommends the Sora 70 instead. [Source](https://www.reviewed.com/cleaning/content/beatbot-aquasense-x-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.
