Pros
- Quiet operation compared to typical pool cleaners.
- Strong suction power for thorough cleaning of walls and floor.
- Anti-stuck design with wheel deflector for corner coverage.
- Includes 33ft hoses and easy setup.
- One-year warranty and responsive customer service.
Cons
- Requires a pool pump of at least 3/4 HP or 1600 GPH, not suitable for smaller systems.
- No reviews yet, so long-term reliability is unverified.
- May not handle large debris or heavy leaf loads.
The VINGLI Automatic Wall-Climbing Pool Cleaner is designed for in-ground pools with a pump of at least 3/4 horsepower. It is an affordable, easy-to-install suction-side cleaner that tackles both floor and wall debris, making it ideal for pool owners who want to cut down on manual cleaning time.
Its quiet operation is a standout, as many automatic cleaners produce loud hammering noises. The VINGLI runs silently while its powerful suction pulls in dirt and leaves. The wheel deflector prevents getting stuck in corners, and the scuff-resistant hoses protect your pool's surface.
The cleaner is built with durable materials and comes with ten 3.3-foot hoses totaling 33 feet, providing ample reach. Assembly is straightforward, and the navy blue and white color scheme blends well with most pool environments. The 10-pound weight ensures stable operation without being too heavy.
One limitation is the pump requirement: you need at least a 3/4 HP pump or 1600 GPH flow rate, which may not work with smaller pumps. Also, as a new product with no user reviews yet, long-term durability is unconfirmed. It may struggle with very large debris.
Overall, the VINGLI Pool Cleaner offers excellent value for its price, combining quiet performance, wall-climbing ability, and a generous hose set. If your pump meets the requirements, it is a solid choice for keeping your pool clean with minimal effort.
Pros
- Powerful dual-centrifugal pump delivers superior suction for tough debris
- Large 4.1L filter basket reduces how often you need to empty it
- Continuous AC power eliminates charging wait and extends runtime
- Smart HydroCurve navigation with auto-docking simplifies operation
- Comprehensive 2-year warranty adds peace of mind
Cons
- 40ft cord limits cleaning radius for very large pools
- Requires a nearby outdoor power outlet, no battery backup
- Higher upfront cost compared to basic suction-side pool cleaners
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.

Buying Guide
Cleaning Coverage and Navigation
When choosing an inground pool vacuum, the ability to clean all surfaces thoroughly is important. Look for models that can climb walls and scrub the waterline, as this prevents algae and scum buildup. The Chasing Hydro 4 and its variants use smart navigation to cover over 95% of your pool, while the Hayward AquaNaut 400 uses pre-programmed steering sequences for complete coverage. For pools with complex shapes, a cleaner with advanced path planning is essential.
If you have a large pool, consider models with longer cables or battery life. The Chasing Hydro 4 Corded version offers a 49-foot cord, ideal for pools up to 1076 square feet. For more on large pool cleaners, check our best robotic pool cleaner for 30000 gallon pool guide.
Suction Power and Filtration
Powerful suction ensures that dirt, leaves, and fine debris are removed efficiently. The Chasing Hydro 4 models boast dual turbine pumps with up to 5070 GPH suction, while the Hayward AquaNaut 400 uses a patented V-Flex turbine to prevent clogs. A large filter basket, like the 4.1-liter basket found in the Chasing Hydro 4 series, reduces the frequency of emptying and captures everything from large leaves to fine silt.
For pools that collect heavy debris, a cleaner with a high-capacity basket and fine filtration is a must. The VINGLI Pool Cleaner, while budget-friendly, relies on your pool’s pump for suction, so ensure your pump is strong enough.
Ease of Use and Maintenance
A pool cleaner should simplify your life, not complicate it. Cordless models like the Chasing Hydro 4 Floating Battery offer convenience without a tether, but require charging. Corded models provide continuous power but may have cable management concerns. Look for features like auto-parking, app control, and easy filter access. The Chasing Hydro 4 SE, for example, offers an auto-docking feature for effortless retrieval.

Durability and Warranty
Investing in a pool cleaner means expecting it to last. The Chasing Hydro 4 series features corrosion-resistant motors suitable for saltwater and chlorinated pools. The VINGLI cleaner comes with a one-year warranty, while Chasing offers up to two years on some models. The Hayward AquaNaut 400 is built with heavy-duty materials and is known for its longevity.
