As a new homeowner who loves to host friends and family, having one less thing to worry about before guests show up has made my pool-cleaning robot well worth it. 

In fact, in my early days of pool ownership, I used a professional cleaning service and ended up spending more in three sessions than the cost of the Dolphin Nautilus CC Plus Wi-Fi. Pool cleaning is now something I barely think about. When the warm weather hits, I can count on sparkling water and a clean pool floor. 

After testing more than a dozen of the best robot pool vacuums, I settled on the Dolphin model because it hits all the marks for cleaning, scheduling via app, low maintenance, and it doesn’t cost an outrageous sum.

My experience with the Dolphin Nautilus CC Plus Wi-Fi

Out of the box, the robot requires no setup other than plugging into a power source 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 only function it doesn’t have 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. 

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 robot pool cleaners I tested.

At 35 pounds, the robot is easy enough to pull out of the pool when it needs to be emptied and rinsed, roughly once a month. Its cord allows you to haul it in without a struggle. Speaking of the cord, the anti-tangle device with attached buoys kept it from looping around itself, although sometimes it gets caught up in my solar robot skimmer. 

Pool filters are not cheap and can be difficult to clean, depending on the type. Having a robot cleaner that works daily will save your filter lots 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, sending less debris through the pipes to be filtered out.

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 have tested more than 12 pool-cleaning robots, and the Dolphin is my top 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 costs half the price of 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.
