- The cord never tangles.
Nobody gets a pool for the extra work, but the work is real. Before robotic cleaners came along, the only options were wrestling with a manual vacuum or paying a premium for a professional to handle it. Those days are behind us. Autonomous pool vacuums do the heavy lifting so you can spend more time in the water and less time fishing debris off the bottom.
But good pool robot vacuums aren’t cheap, so I don’t recommend buying whatever comes up on your Amazon search. Don’t worry, we’ve done the legwork so you don’t have to.
I tested a slate of 20 robot pool vacuums in 2026 to find the best, and the Dolphin Nautilus CC Plus Wi-Fi took the top spot for corded models. It cleans my entire 14,000-gallon pool in under two hours, lets you schedule cleanings via app, and costs significantly less than you’d expect given how well it performs.
While a new cordless model, the Aiper Scuba V3, takes the crown as the best overall pool robot, those who don’t want to worry about charging between cycles will be glad to bring the Nautilus corded model into the fold. The Dolphin Nautilus CC Plus Wi-Fi hits all the marks for cleaning and scheduling via its app, and it doesn’t cost an arm and a leg.
Here’s everything you need to know.
Why I chose the Dolphin Nautilus CC Plus Wi-Fi
The Dolphin deftly cleaned my pool floor and sides in about two hours.
Out of the box, the robot requires no setup other than plugging in and connecting to Wi-Fi, a process that took me less than 5 minutes. Once it’s connected, dropped in the pool and a cleaning schedule is set, there’s not much else to do.
The CC Nautilus Plus Wi-Fi cleaned my pool in around 2 hours, picking up soggy leaves, dead bugs, gravel and sand. It used its fierce scrubbing brushes and a suction rate of 4,500 gallons per hour to clean the floor and walls of my kidney bean-shaped pool.
The cord occasionally hooked the solar skimmer bot, but that didn’t cause any complications.
There’s no waterline cleaning, but it doesn’t bother me
The only function it lacks is a dedicated waterline setting, but I’ve found most waterline-cleaning features to be just OK. Plus, it’s easy enough to brush the waterline manually every few weeks if you notice buildup. For me, spending several hundred dollars more for a model with waterline cleaning just isn’t worth it.
Being able to set a cleaning schedule from my device tipped this robot cleaner over the line for me.
The Wi-Fi and app connectivity are what tipped this model over the top. Through the app, you can control the robot’s cleaning schedules, and I found it had far fewer disconnections and glitches than other connected pool-cleaning robots I tested.
The cord makes retrieving the robot easy
At 35 pounds, the robot isn’t the lightest we tested, but it’s easy enough to pull out of the pool for emptying and rinsing. Its cord allows you to haul it in without a struggle. Speaking of the cord, the anti-tangle device with attached buoys keeps it from looping around itself, though it sometimes gets caught up in my solar robot skimmer.
A pool robot that filters water means far less stress on your expensive built-in equipment.
The fine filter takes some of the load off your main equipment
Pool filters are not cheap and can be difficult to clean, depending on the type. Having a robot cleaner that runs daily will save your filter a lot of work and prevent you from having to replace it as often. It’ll also take some stress off your built-in pool pump and filtration system, reducing the amount of debris that passes through the pipes.
You can bypass the app and use the control box to start and stop the robot.
Cleaner water also means you’ll spend less on chemicals due to a reduction in algae growth and better water chemistry balance.

CNET’s buying advice
I’ve tested nearly two dozen pool robots and learned a few things along the way.
I have tested 20 pool-cleaning robots, and the Dolphin is my top corded recommendation. It does everything you need it to, including deep cleaning of the walls and floor on a schedule of your choosing. It’s easy to use and maintain, and it costs half as much as competitors’.
If you factor in how much time a robot pool cleaner saves or what you’d have to pay for professional vacuuming, this is as close to a no-brainer as purchases get for pool owners.
