EON 120d

The DebrisLock basket retained grit effectively in the test. Overall pickup was good, but some leaves remained on steps and in recurring corner gaps. Strong filtration should therefore not be confused with reaching every part of the pool.

The review unit twice failed to begin cleaning before a full power cycle resolved the immediate problem. It also tipped over frequently but righted itself. Those observations describe the tested unit; they do not establish a permanent defect in all production machines.

The supplied clicker reliably called the robot to the waterline and was easier than fishing with a hook. Conversely, the tightly retaining filter was difficult to clean. That trade-off matters if your pool collects fine dirt every day.

The test concerns the 120d, whose filter differs from the EON 100. It uses Maytronics One rather than MyDolphin Plus. Long-term reliability remains outside this hands-on test’s evidence.

An owner explicitly naming the EON 120D reports that it stopped after its first clean and would not reconnect over Wi-Fi or Bluetooth. They also report unsuccessful step climbing, difficulty reaching human support and a refund after returning it. This is an unprompted owner report, not a verified failure-rate study.

A French EON 120d owner reports returning a robot that spun in place, inconsistent routes and limited step access. They also found its pleated filter cumbersome and lifting it heavy. These complaints warrant attention without proving that every unit develops them.
