The Chasing Hydro 4 SE is a robotic pool vacuum engineered for inground pools, delivering powerful triple-action cleaning across the floor, walls, and waterline. It is best suited for residential pool owners who want a corded, low-maintenance solution without the hassle of battery charging.
Its dual-centrifugal pump system generates impressive suction, easily handling fine sand, leaves, and debris. The 4.1L dual-zone filter basket is exceptionally large, meaning fewer interruptions to empty the canister, and the optional 50-micron filter polishes the water to crystal clarity.
HydroCurve navigation technology ensures complete coverage and smooth transitions from floor to wall, while the auto-docking feature returns the unit to the pool edge for effortless retrieval. The lightweight 6.5kg body and tangle-resistant 40ft cable make setup and operation straightforward.
The main limitation is the 40ft cord, which may not cover very large inground pools without repositioning the power unit. Additionally, because it runs on continuous AC power, you need a convenient outdoor outlet, and the initial investment is higher than basic suction-side cleaners.
Overall, the Chasing Hydro 4 SE is a reliable, feature-packed robotic cleaner for most inground pools. With continuous power, intelligent navigation, and a generous warranty, it is a strong choice for pool owners who value consistent performance and minimal upkeep.

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
Power and Suction Performance
The heart of any corded pool cleaner is its motor and suction power. Models like the Chasing Hydro 4 SE use dual centrifugal pumps to generate massive water flow, often exceeding 5,000 gallons per hour. This high suction is critical for lifting heavy leaves, sand, and gravel from the pool floor and walls.
When comparing options, look for units with dual pumps and high GPM (gallons per minute) ratings. This ensures the robot can handle everything from fine silt to large debris without losing performance. For a comparison with other popular brands, read our best seauto seal SE robotic pool vacuum article to see how they stack up.
Navigation and Coverage
A smart navigation system is essential for a thorough clean. The best corded robots use intelligent algorithms to map your pool and follow systematic S-paths or N-paths, ensuring every inch of the floor, walls, and waterline is covered. Features like wall-climbing and waterline scrubbing are crucial for eliminating scum lines and algae.
Look for models with gyroscope or HydroCurve navigation for precise movement and obstacle avoidance. This technology prevents the robot from getting stuck on main drains or ladders. For more on navigation technology, explore our ROBOTIC POOL CLEANERS category page for a broader overview.
Filtration System
The filter basket is your first line of defense against debris. A large capacity basket, ideally 4.1 liters or more, means less frequent emptying. Fine mesh filters (around 180 microns) capture tiny particles, while some models offer optional ultra-fine filters for crystal-clear water.
Top-loading baskets are the most convenient, allowing you to remove debris without getting your hands dirty. Consider the ease of cleaning and the availability of replacement filters when making your choice. For a different perspective on filtration, check out our Above Ground Pool Cleaners guide for related tips.
Durability and Warranty
Investing in a robotic pool cleaner means expecting years of reliable service. Look for models with corrosion-resistant motors and high-quality materials that can withstand chlorine, salt, and UV exposure. A solid warranty, such as a 2-year parts and labor guarantee, provides peace of mind.
Brands like Chasing and Dolphin have strong reputations for durability. Reading user reviews and checking the warranty terms can help you avoid costly repairs down the line. For a comparison of different brands, see our aiper vs betta article for insights on long-term value.
Final Thoughts
After evaluating the top corded robotic pool cleaners, the Chasing Hydro 4 SE Pool Vacuum for Inground Pools stands out as the best overall choice for its powerful dual-pump suction, intelligent navigation, and massive 4.1L filter basket that handles heavy debris with ease.

Frequently Asked Questions
How long does a corded robotic pool cleaner last?
Most corded pool cleaners have a lifespan of 3 to 5 years with proper maintenance. In 2026, models like the Chasing Hydro 4 SE feature corrosion-resistant motors that can handle saltwater and chlorine exposure, extending their useful life. Regular cleaning of the filter and inspecting the cable for wear will help maximize durability.
Can a corded pool cleaner handle large debris like leaves and acorns?
Yes, corded models with dual pump systems, such as the Chasing Hydro 4 SE, are specifically designed for heavy debris. With suction rates exceeding 5,000 GPH and large filter baskets, they can easily pick up leaves, acorns, sand, and even small stones. The continuous power supply ensures they maintain full suction throughout the entire cleaning cycle.
Is a corded pool cleaner better than a cordless model?
It depends on your pool size and cleaning needs. Corded models offer unlimited runtime and consistent suction, making them ideal for large inground pools or heavy seasonal cleaning. Cordless models, like the Chasing Hydro 4 Cordless, provide convenience without a cable but have limited battery life. For most homeowners with inground pools, a corded cleaner offers superior performance and reliability. For a deeper comparison, check out our Best Zodiac Pool Cleaner with Advanced Features guide.
How do I maintain my corded robotic pool cleaner?
Routine maintenance is simple. After each use, empty and rinse the filter basket. Inspect the brushes for tangled hair or debris and clean them as needed. Store the unit out of direct sunlight and ensure the power cable is coiled loosely to avoid kinks. Following these steps will keep your robot running efficiently for years.
