- Filter basket may need frequent emptying if pool is heavily debris-laden.
The Dolphin Nautilus AG (2026 Model) is a robotic pool vacuum tailored specifically for above-ground pools up to 33 feet in length. It aims to eliminate the manual drudgery of pool maintenance with a combination of an active scrubber brush and smart navigation. This is a solid choice for pool owners who want a set-it-and-forget-it solution without breaking the bank.
Standout features include the active scrubber brush, which actively agitates dirt and debris from pool surfaces, and the top-load filter basket that makes emptying a breeze. In practice, the robot navigates intelligently, scanning the pool to determine the most efficient cleaning path. While it does not clean walls or the waterline, it does a thorough job on the floor and coves, completing a cycle in roughly 1.5 hours.
Design and build quality reflect Dolphin's 40-year legacy. The unit feels solid yet lightweight at just under 15 pounds. The plug-and-play system means no complicated installation: simply connect the power supply, lower the robot into the water, and turn it on. The top-load filter is a thoughtful ergonomic touch, allowing you to remove debris without bending or flipping the unit.
Potential drawbacks are worth considering. The lack of wall and waterline cleaning means you'll still need to manually brush those areas. Also, the robot does not offer scheduling via an app or remote – it runs a fixed cycle each time you plug it in. For pools with heavy leaf or debris loads, the filter basket may require frequent emptying during the cycle.
Overall, the Dolphin Nautilus AG delivers on its promise of effortless floor cleaning for above-ground pools. It earns a 4-star rating for its reliability, user-friendliness, and performance. If you don't mind occasional manual touch-ups on walls and are looking for a straightforward, effective robotic cleaner, this is a strong investment.
Buying Guide: What to Consider When Choosing Between Dolphin and Hayward
Cleaning Technology: Robotic vs Suction-Side
The fundamental difference lies in how each system operates. Dolphin cleaners are robotic: they run on low-voltage electricity, have their own motor, pump, and filter, and require only a connection to a power supply. They operate independently of your pool’s circulation system. Hayward cleaners, on the other hand, are suction-side units that attach to your skimmer or dedicated suction port. They rely on your pool pump to create suction, which moves the cleaner across surfaces. Robotic models like the Dolphin Automatic Robotic Pool Vacuum Cleaner offer energy efficiency and thorough scrubbing, while Hayward units like the Hayward TracVac Automatic Pool Vacuum for Inground leverage your existing pump, which can be cost-effective if you already run it frequently.
Pool Compatibility: Size, Shape, and Surface
Not every cleaner fits every pool. Dolphin models, such as the Dolphin Nautilus CC Plus, are designed for in-ground pools up to 40 feet in length and work on all surfaces (concrete, fiberglass, vinyl, tile). They climb walls and scrub the waterline, making them ideal for irregular shapes. Hayward offers models for different pool sizes: the two-wheel Poolvergnuegen is for pools up to 16×32 feet, while the four-wheel version handles up to 20×40 feet. If you have an above-ground pool, the Dolphin Nautilus AG is specifically built for that application. Always match the cleaner to your pool’s dimensions and surface type to avoid poor coverage or damage.
Ease of Use and Maintenance
Robotic cleaners earn high marks for convenience. You simply plug them in, drop them in the water, and let them run for a couple of hours. The top-load filter basket on Dolphin models makes debris removal quick and clean. Suction-side Hayward cleaners require connection to your pool’s plumbing, which may involve adjusting valves and ensuring adequate flow. They also rely on your pump’s runtime, so you may need to run your pump longer. For beginners, a robotic Dolphin is often the more straightforward choice. Our guide on the best Dolphin robotic pool cleaners for beginners can help you get started.
Navigation and Coverage
How thoroughly does the cleaner cover your pool? Dolphin robots use smart navigation (some with Wi-Fi scheduling) to scan the pool and determine an efficient cleaning path. They climb walls, scrub the waterline, and handle steps. Hayward suction cleaners use pre-programmed steering sequences and patented tire treads to change direction and climb walls, but they may miss some spots if flow is inconsistent. The Hayward AquaNaut 400, for instance, has a V-Flex turbine that maintains power at variable flow rates. For large or complex pools, a robotic Dolphin with advanced navigation may provide more reliable coverage. If you value remote control, explore our dolphin nautilus EON 120D review for a cordless option.
Final Thoughts
Choosing between Dolphin and Hayward ultimately comes down to your pool setup and your willingness to manage the cleaning process. If you want a hands-off, energy-efficient cleaner that handles walls, waterline, and fine debris on its own schedule, the Dolphin Automatic Robotic Pool Vacuum Cleaner is a top performer with proven reliability. If you prefer a more affordable, pump-driven solution that integrates with your existing system and works well on floors and walls, the Hayward TracVac Automatic Pool Vacuum for Inground delivers solid coverage without the need for extra power. Both brands have strong track records, so you can feel confident whichever path you take.

Frequently Asked Questions
Which is better, Dolphin or Hayward pool cleaner?
It depends on your priorities. Dolphin robotic cleaners offer independent operation, wall climbing, and fine filtration with minimal effort. Hayward suction cleaners are generally less expensive upfront and use your pool pump, but they may require more attention to hose routing and flow balance. For most pool owners in 2026, a Dolphin robot provides the best balance of convenience and performance.
Can a Hayward suction cleaner clean walls?
Yes, many Hayward models, such as the Poolvergnuegen and AquaNaut series, are designed to climb walls. They use patented tire treads and internal steering sequences to navigate vertical surfaces. However, the effectiveness depends on your pump’s flow rate and the pool’s surface texture. Robotic Dolphins generally have a stronger wall-climbing capability due to their dedicated motors.
Do Dolphin robotic cleaners need a booster pump?
No. Dolphin robotic pool cleaners are completely self-contained. They have their own motor, pump, and filter, so they do not require a booster pump or any connection to your pool’s circulation system. Just plug the power supply into a standard outlet, place the unit in the water, and it starts cleaning immediately.
How often should I run my pool cleaner in 2026?
During peak swimming season, running your cleaner daily or every other day is recommended to keep debris under control. Robotic Dolphins can be scheduled via Wi-Fi (on models like the Nautilus CC Plus Wi-Fi) to run automatically. Suction-side Hayward cleaners run whenever your pump is on, so adjust your pump timer accordingly. For lighter usage, two to three times per week may suffice.
