Dolphin Nautilus CC Plus Wi-Fi Automatic Robotic Pool Vacuum Cleaner, Always Cleaning, Never Charging, with Wall Climbing Scrubber Brush, Ideal for In-Ground Pools up to 40 FT in Length

This is a big strong pool cleaning corded robot. It really quickly cleans my 33,000 gallon pool. It is for a strong person. I am 85 years old so if you are robust you will be fine... if not recognize that, especially when you want remove it from the pool full of water. Cordless is more of a hassle but I am glad I chose it because it has the juice to attack the surfaces of the pool and that is what I want. The cord manages itself very well and normally stays out of its own way. For 41 years I made do with a water driven vacuum wimp that went around and around totally confused sometimes still missing sections... good riddance.

This is a simple, well performing machine. Buyers should be aware this unit is not programmable and it moves in a random pattern around your pool bottom. But it works just fine, at a cheaper price. It is not advertised as a waterline scrubber, but it does break the waterline and scrubs. Good value! Make sure your electrical outlet is situated in a place that allows the vacuum to reach all parts of your pool, as extension cords are strongly discouraged by the manufacturer.
