The Ecovacs Ultramarine P1 is a robotic pool cleaner designed to clean both the bottom and the walls of a swimming pool. Priced at 398.99 euros on Amazon—down from 549 euros—it offers a cost-effective solution for pool maintenance. The robot can climb the sides of the pool, but it may struggle with steps, sometimes getting stuck when trying to move vertically. The device offers three cleaning modes and three levels of suction power. However, using higher suction settings reduces the robot's battery life, limiting how long it can operate before needing to be recharged. It is equipped with two filters: a fine 3-micrometer filter for capturing small particles and a larger 180-micrometer filter for catching bigger debris like leaves. Despite its relatively heavy weight of 10.5 kilograms, it includes a handle for easy removal from the pool after cleaning. Users can control the robot via the Ecovacs mobile application, where they can choose cleaning modes and adjust suction power. The robot can clean pools up to 180 square meters and has a maximum operating time of three hours. However, once its cleaning cycle is complete, it does not automatically return to the surface and must be manually retrieved using a hook provided in the package. One notable limitation is the absence of obstacle detection, which could cause the robot to run into objects or get stuck in certain environments. While the Ecovacs Ultramarine P1 is a versatile and affordable option for pool cleaning, these limitations should be considered before purchasing.
