## Key takeaways

- **Corded** robots run as long as they're plugged in and have the longest owner records; **cordless** robots have no cable and newer features but need charging.
- Most corded Dolphins **don't clean the waterline** and have no app; most newer cordless robots do both.
- Cordless robots depend on a **lithium battery** that wears with charge cycles; corded robots have a cable and swivel to look after.
- Price is similar at the mid-range (**~$800–850** for the CC Plus and AquaSense 2); the cordless premium shows up for the same suction.

The first decision in buying a pool robot is also the biggest one: plug-in or battery. A corded robot like the Dolphin Nautilus runs from a poolside power supply; a cordless one like the Beatbot AquaSense 2 or Aiper Scuba S3 runs on a rechargeable battery. They overlap on price and cleaning ability, so the choice comes down to how you want to live with the robot.

  Three kinds of pool robot They solve different problems — and plenty of pools use two of them.

        Corded vacuum robot
        Plugs into a poolside power supply and runs as long as you want. Strong, proven, no battery to degrade — but you manage a floating cord and lift 20+ lbs out of the water.

         Dolphin Nautilus CC · CC Plus · CC Supreme · Nautilus AG

        Cordless vacuum robot
        A rechargeable battery gives 1.5–5 hours per charge and no cord. Newer models climb walls, scrub the waterline and park themselves at the surface — but you recharge every use or two.

         Beatbot · Aiper Scuba · Wybot · Seagull SE

        Solar skimmer
        Floats on the surface, skimming leaves, pollen and bugs all day on sunlight. It does not vacuum the floor or climb walls, so it complements — rather than replaces — a vacuum robot.

## Quick comparison

| | Corded | Cordless |
| --- | --- | --- |
| Runtime | As long as it’s plugged in | ~1.5–5 hr per charge (rated) |
| Waterline cleaning | Rare (CC Supreme only among our Dolphins) | Common in newer models |
| App / scheduling | Mostly no (CC Supreme has Wi-Fi) | Common |
| Handling | Cable to manage; 20+ lb wet robot | No cable; parks itself on newer models |
| Wear items | Cable, swivel, tracks, brushes | Battery, tracks, brushes |
| Owner record | Long (CC Plus ~14,000 reviews) | Short (most launched 2025–2026) |
| Warranty | Typically 1 year (Dolphin Nautilus) | 2–3 years common |
| Mid-range price | ~$600–850 | ~$450–850 |

## Cleaning power

Corded robots have a reputation for stronger suction and consistent runs, since they’re fed continuous power; some reviewers who tested many robots still prefer corded for floors. Newer cordless robots have closed much of the gap on suction (the Beatbot Sora models list 6,800 GPH) but can lose runtime on heavily soiled pools and wall-climbing modes. The main practical difference is surfaces: the [Nautilus CC Plus](https://robotpoolcleanerguide.com/pool-robots/dolphin-nautilus-cc-plus/) cleans floors and walls only, while most cordless robots also clean the waterline.

## Runtime

Corded robots run a full cycle (about 2 hours for the CC Plus) every time. Cordless runtimes are manufacturer best-case figures; see [coverage ratings explained](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-coverage-ratings-explained/) for why you should expect less. In practice a typical pool is cleaned in one run per charge, but that means recharging after almost every use. If you want to run it daily without thinking, corded is simpler.

## Handling

Cordless robots are easier to deal with: no cable to untangle, many park themselves at the waterline or surface ([AquaSense 2](https://robotpoolcleanerguide.com/pool-robots/beatbot-aquasense-2/), [Scuba S3](https://robotpoolcleanerguide.com/pool-robots/aiper-scuba-s3/)) and some drain internal water before lifting. Corded robots mean a floating cable and a power supply near the pool. Both types are heavy when wet.

## Reliability and lifespan

Corded robots have the longer track record and no battery to wear out, but a cable and swivel that can kink or crack, and shorter warranties. Cordless robots avoid the cable, but lithium batteries lose capacity with charge cycles and heat. Beatbot’s blog cites roughly 1,000 cycles; that’s a manufacturer claim. Because most cordless models are new, long-term data doesn’t exist yet. We cover it in [how long robotic pool cleaners last](https://robotpoolcleanerguide.com/posts/how-long-do-robotic-pool-cleaners-last/).

## Who should buy which

Buy corded if you want the proven option, run the robot often, don’t need the waterline cleaned and don’t mind a cable. See the [Nautilus CC Plus](https://robotpoolcleanerguide.com/pool-robots/dolphin-nautilus-cc-plus/) and our [CC Plus vs AquaSense 2 comparison](https://robotpoolcleanerguide.com/posts/dolphin-nautilus-cc-plus-vs-beatbot-aquasense-2/).

Buy cordless if you want no cable, waterline cleaning, app scheduling and a longer warranty, and you’re comfortable charging. Start with the [best cordless robotic pool cleaners](https://robotpoolcleanerguide.com/posts/best-cordless-robotic-pool-cleaners/).

Above-ground pool? A cheap cordless floor cleaner is often enough; see the [above-ground guide](https://robotpoolcleanerguide.com/posts/best-robotic-pool-cleaner-for-above-ground-pools/).

## Frequently asked questions

### Are corded pool robots better than cordless?
It depends on what you value. Corded robots offer unlimited runtime, strong suction and the longest owner records. Cordless robots are easier to handle, have no cable to manage and add waterline cleaning, apps and parking. For a typical in-ground pool both work.

### Do cordless pool robots have enough battery for a full cleaning?
For most pools, yes. Rated runtimes run roughly 1.5–5 hours; a typical pool needs less. Large pools or heavy debris may need two runs.

### Do corded pool robots need a power supply?
Yes. A corded robot connects to a low-voltage power supply that plugs into a grounded outlet near the pool, and a cable runs to the robot. Follow the manual's placement and electrical safety guidance.

### Which type lasts longer?
Neither maker publishes lifespans. Corded robots have no battery to wear out; cordless robots' lifespan depends on charge cycles. See how long robotic pool cleaners last.
