Charger is missing Automatic Pool Cleaning: Two large suction doors work with one bottom brush to trap and lock in leaves, dirt and sand, leaving your pool beautifully clean. Tangle-Free: With a cordless design, it can freely cover the entire pool area without worrying about the risk of wire entanglement, while preventing the control boxes from getting wet or being dragged into the pool. Efficient & Time-Saving: The robotic pool cleaner can be quickly started up by turning the knob for up to 90-minute efficient cleaning without manual supervision. Suitable for All Kinds of Pools: Ideal for residential flat bottom pools of all shapes. Cleaning surface up to 860 Sq. Ft and water depth of 6.6ft (2M). This pool cleaner is only suitable for flat-bottom swimming pools, not climbing walls or slopes more than 15-degrees. Safety for all surfaces, such as concrete, fiberglass and vinyl liner pools. Intelligent & Convenient Use: When the cleaning cycle is complete or the battery is low, the machine will automatically stop to the side; you can easily remove the cleaner machine from the pool by pulling the floating handle, then rinse the internal dirt and dry it. Warm Tips: Please read the user manual before using it for the first time.
