The Dolphin Nautilus CC Plus is our favorite model due to its easy programming, energy-efficient operation, and top-load filter cartridges. The next-best model is the Dolphin Premier Robotic. It has the option to use filter cartridges or a leaf bag, an extremely efficient motor, and a three-year warranty. The Polaris Vac-Sweep 360 takes third place with its easy installation and great performance with larger debris. Its low price makes it the best overall value for the money.
The Hayward AquaNaut 400 earns fourth place with its four-wheel drive and great roller skirt, though it struggles with walls. The Polaris F9550 Sport Robotic In-Ground Pool Cleaner comes with robotic operation and Aqua-Trax tires, but its high price and issues with walls hurt its value. In sixth, the Hayward Poolvergnuegen ‘The Pool Cleaner’ has self-adjusting turbine vanes and pre-programmed steering sequences, but it has problems with walls and algae.
The Zodiac Baracuda G3 works with low-speed pumps and has good performance in corners, but issues with assembly and stairs drop it to seventh place. In eighth, the Pentair LL505G Kreepy Krauly is great for darker pools and features a stable wheel design. However, it has a high price and requires a booster pump.
The Zodiac Baracuda MX6 works well with low-flow pumps and is good at climbing walls, but its poor durability and propensity for getting stuck really hurt its value. Last place is taken by the XtremepowerUS 75037. It has easy assembly and a low price, but buyers should be cautious about its frequent jamming and overall low quality.
