Bought this for our new pool in June of 2017. It really does a nice job.Were worried about the longevity of the robot and quality of the clean, versus a traditional hose vacuum (which frankly, sounded like a nightmare). This cleaner is a big help. I drop it in before I leave in the morning and its finished when I get back home. Simple to recharge. Really reduces the amount of time .I save myself the time and elbow grease. I’ve been able to spend a lot more time in the pool since buying this. One of the best purchases I’ve ever made.
