The answer
What to know.
How it cleans pool steps
The EON™ 100/120d uses JETIQ technology to direct water through a servo. This controlled water flow helps the robot climb pool steps and remove debris.
The robot detects the first step, climbs to the top, and cleans the top step. It then descends one step at a time, cleaning each stair along the way.
When it reaches the bottom, it repeats the sequence for a second cycle, then finishes with a final climb to the top. The robot can repeat this process up to 3 times, for a total cleaning time of 12 minutes.
How it cleans the sun ledge
The robot is designed to clean sun ledges in water as shallow as 8 inches. Its dual-drive brushes clean the surface as it moves across the ledge for consistent, edge-to-edge coverage.
Intelligent detection technology helps the robot maintain its position and navigate the ledge smoothly. It can also return to the ledge as needed to complete its coverage.
