- Customer feedback is limited at this time, so long-term reliability is not yet independently verified
The EZIOOV U8 is a cordless robotic pool cleaner built for owners of medium to large inground pools up to 2,600 square feet. It is designed for anyone who wants automated cleaning of the floor, walls, and waterline without dragging hoses or spending weekends brushing. With a 150-minute runtime, the U8 can handle weekly maintenance in a single charging cycle.
The standout feature is wall and waterline scrubbing. Triple brushless motors and strong traction allow the robot to climb surfaces and remove grime, oil, and stuck-on debris that usually requires hand work. Gyroscope and ultrasonic sensors help it follow efficient paths and avoid obstacles while covering deep ends, corners, and ladder areas.
The 26-pound body feels solid in the pool, and the quick-drain design makes lifting easier after the cycle ends. Its 4-liter top-load filter catches fine dirt, sand, leaves, and larger debris, and you can empty the basket without turning the unit over. The carbon black finish looks clean, and a simple one-button control keeps the experience straightforward.
The main limitations are the lack of remote control or app scheduling and the unit's weight when removed from a deep pool. You choose a mode by pressing the button and let the robot do its work, but there is no way to steer it manually. Since this model has limited customer feedback available, long-term durability is not yet verified by extensive real-world use.
For pool owners who prioritize cordless freedom, wall scrubbing, and a long runtime, the EZIOOV U8 is a strong option. It simplifies routine maintenance and eliminates the tangles and setup of corded units. If you have a larger inground pool and prefer one-button automation, the U8 is worth serious consideration.
