Frequently Asked Questions

What does the sensor block do on a Zodiac robotic pool cleaner?

The sensor block detects obstacles such as pool walls, steps, and fittings, and sends signals to the cleaner's controller to adjust its navigation path. A faulty sensor block causes the cleaner to move erratically, get stuck, or miss areas of the pool.

How do I know if my sensor block needs replacing?

Signs include the cleaner repeatedly getting stuck in the same spot, erratic or random movement patterns, or failure to cover the full pool surface.
