What reviewers found
Ecovacs Ultramarine P1
- The Hook Up: Ran 2 h 9 min and covered 99% of the floor, 81% of walls and 38% of stairs and bench. Reached the coping at the waterline, captured silt well with the floss filter and leaked zero particles, but has a small bin and climbed the 8 in shelf enough to raise concern it could climb out. Named budget pick for sand, silt and pollen. Source
- EFTM (87%): Cleaned the test pool spotless in about 90 minutes and climbed walls and a two tier step. Charging from 5% to full took 3 h 40 min. Flipped upside down once after a wall climb. Source
Wybot C2
- Bob Vila: Named Best for Fine Debris in a hands on roundup; about 2 h of battery life against a 185 min table figure, with ratings of 4.8 for ease of use, 4.5 for performance and 4 for value. Source
- The Pool Nerd: Labeled Pool Nerd Disapproved. In an 8 x 20 ft pool it ran 180 min floor only but about 60 min in Turbo, needed about 3 h to recharge after each cycle, and its weekly timer caps total runtime at 180 min. Suction of 3,592 GPH trailed corded Dolphin rivals. The site prefers corded robots. Source
