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
- 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
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
