Owning a pool is great, but keeping it clean can feel like a chore. Robotic pool cleaners are here to make life easier. They scrub the floor, climb the walls, and pick up debris while you relax. But there is one big question pool owners face: Should you buy a corded robotic pool cleaner or a cordless one?

Both options have strong points. Both also have weak spots. The right choice depends on your pool, your budget, and how much convenience you want. In this article, we’ll break down the pros and cons of each type, share real user experiences from Reddit, highlight expert reviews from trusted sources, and finally reveal which option most pool owners call the winner.

Corded Robotic Pool Cleaners

Corded robotic pool cleaners have been around for years. They plug into a power supply outside the pool and run on electricity. A long waterproof cable connects the robot to the power unit.

Pros of Corded Cleaners

1. Strong cleaning power
   Corded cleaners usually come with powerful motors and strong suction. They can scrub walls, floors, and even the waterline. Many pool owners on Reddit say their corded Dolphin cleaners run for years and never lose power.

2. Consistent performance
   Because they run on electricity, corded robots do not slow down over time. There’s no battery to worry about. One Redditor summed it up: “Every customer that gets a corded Dolphin LOVES it.”

3. Longer cleaning cycles
   Corded robots can run for several hours at a time. You can also set them on timers. That means you can leave them in the pool and let them do the job automatically.

4. No battery issues
   Batteries wear out. They lose capacity and cost money to replace. Corded models skip that problem completely.

5. Durability
   Most corded cleaners last longer than cordless ones. They are designed for heavy use, and some models even come with three-year warranties.

Cons of Corded Cleaners

1. Cable management
   The cord can tangle. While many new models have swivel cables to reduce this, it is still something you need to watch.

2. Pool cover problems
   If you use an automatic pool cover, the cable can get in the way. One Reddit user explained: “I leave my autocover open an inch so as not to pinch the cord.” Another said they simply close the cover onto the cord, which is not ideal.

3. Less portable
   Corded cleaners are heavier and a little harder to set up. You need to place the power supply on the pool deck and unwind the cord each time.

Cordless Robotic Pool Cleaners

Cordless robotic pool cleaners are the new trend. Instead of plugging into a power supply, they run on rechargeable batteries. You drop them in the water, press start, and let them run.

Pros of Cordless Cleaners

1. Easy setup
   With no cord to deal with, setup takes just seconds. Drop the cleaner in and it goes to work.

2. Freedom of movement
   Because they are cordless, these robots don’t get tangled up. They move around the pool more freely.

3. Great for small pools
   For smaller pools or above-ground pools, cordless cleaners can be very convenient. You don’t need as much power, and the shorter run time isn’t a big issue.

4. New smart features
   Some new cordless models now include advanced technology. For example, the Beatbot AquaSense 2 Ultra uses AI to map your pool and adjust its cleaning path. High-end models are closing the gap with corded robots.

Cons of Cordless Cleaners

1. Battery limits
   Most cordless cleaners run for only 60–90 minutes before they need to recharge. One Reddit user complained: “At full charge it would run for 90 minutes and die.” For big pools, that is often not enough.

2. More manual work
   After every cleaning cycle, you must take the cleaner out, empty the basket, and recharge the battery. With corded models, you can just leave them in the pool on a schedule.

3. Weaker suction
   Because they rely on batteries, cordless cleaners usually have less suction power and weaker filters. They may struggle with heavy debris or very dirty pools.

4. Shorter lifespan
   Over time, the battery wears out. Replacement batteries are expensive, and some models cannot be replaced easily. That means you may need to buy a whole new cleaner sooner.

Reddit is full of pool owners sharing their honest opinions. Here are some highlights:

• Corded love: Many pool owners say corded Dolphin models are the most reliable. One wrote, “Everyone that gets a cordless vacuum, never uses them and they eventually get rid of them.”

• Cordless frustration: Some people tried cordless robots but gave up. One said, “Cordless robot run times are trash.”

• Pool cover tricks: Users with automatic covers have found ways to work around cords, like leaving the cover open a little or letting the cord pinch under the cover.

• Battery concerns: Even people who like cordless cleaners admit the battery is the weak link. They worry about replacement costs and short run times.

Expert Reviews & Market Insights

Beyond Reddit, product reviewers and experts have tested both types:

• The Spruce compared the Dolphin Nautilus CC Plus (corded) and the Aiper Seagull SE (cordless). The Dolphin was more powerful and reliable, while the Aiper was cheaper but weaker.

• BHG (Better Homes & Gardens) named the Aiper Seagull SE the “best budget cordless” option.

• PoolBots highlighted corded Dolphin ProLine models for their strong motors and advanced filtration.

• People Magazine praised the new Aiper Scuba S1, calling it a big step forward in cordless convenience.

• Tom’s Guide reviewed the Beatbot AquaSense 2 Ultra, noting its AI navigation and built-in skimmer. They even said it was strong enough to replace a $4,000 pool service.

Side-by-Side Comparison

Which One Should You Choose?

The right choice depends on your pool and your needs.

• Choose a corded cleaner if:

  • You have a large pool

  • You want strong suction and deep cleaning

  • You want a robot that lasts for years

  • You want true automation with timers

• Choose a cordless cleaner if:

  • You have a small or medium pool

  • You want the simplest setup possible

  • You don’t mind charging after each use

  • You are interested in new high-tech models with AI features

Conclusion

So, which is better? Corded or cordless?

Based on user experiences and expert reviews, the corded robotic pool cleaner is still the winner today. It is stronger, more reliable, and lasts longer. For most pool owners, especially those with medium or large pools, corded models provide the best value.

That said, cordless cleaners are improving fast. If you own a smaller pool, or you want a super easy setup, a cordless robot could work well. High-end cordless models like the Beatbot AquaSense 2 Ultra show where the future is heading—smarter, more powerful, and easier to use.

In the end, both corded and cordless cleaners make pool maintenance easier. The choice depends on whether you value raw power and long-term reliability, or convenience and simplicity.
