The SE requires a 90-degree wall angle to detect the wall and reverse. Curved or sloped walls prevent the robot from recognizing the boundary correctly. Also check the two water outlet ports for blockages — a blocked outlet reduces the wall-detection bounce.
90-Degree Wall Requirement
The Scuba SE uses its bumper sensor to detect walls and reverse. This works reliably on pools with vertical (90°) walls. If your pool has curved, sloped, or angled walls (common in fiberglass pools), the robot may not register the wall contact correctly and can get stuck against it. This is a hardware limitation of the SE’s sensor system.
Check the Two Water Outlet Ports
The SE has two water outlet ports on the body. If either is blocked, the water jet that assists the bounce-back motion is reduced. Open the robot body, remove the motor cover screws, and inspect the outlets for debris. Clear any blockages and test in the pool.
Ensure Full Charge Before Use
A partially charged battery causes the motor to run at reduced power, which can prevent the SE from generating enough force to push off the wall. Always charge fully (LED returns to green) before placing in the pool.
Stuck in a Corner
The SE has an automatic reverse-and-turn escape routine for corners. Wait 30 seconds before manually retrieving it — the escape cycle may still be active. If it remains stuck after 30 seconds, retrieve and restart from the center of the pool.
