The Hayward Poolvergnuegen 2-Wheel Suction PoolCleaner is a specialized hydraulic vacuum designed specifically for inground pools up to 16 x 32 feet. Unlike traditional 'flipper' style cleaners that can be noisy and prone to clogging, this unit uses a patented turbine system with flexible vanes. This design allows the cleaner to maintain high suction power while easily passing larger debris, making it a reliable 'set and forget' solution for pool maintenance.

One of the standout features of this model is its programmed steering. The internal gear system ensures the cleaner moves 8 to 10 feet before initiating a turn, with turn angles ranging from 90 to 450 degrees. This randomization is crucial for ensuring that the vacuum reaches every corner of the pool floor and doesn't get stuck in a repetitive pattern or trapped against steps and main drains.

The build quality focuses on traction and adaptability. The patented tire treads are designed to climb walls and navigate obstacles that stop other cleaners in their tracks. Additionally, the adjustable roller skirts allow the vacuum to maintain a tight seal against the pool surface, even when moving over uneven areas or transitions between the floor and walls.

While this 2-wheel version is incredibly efficient for standard rectangular or oval pools, owners of larger pools or those with very steep floor-to-shallow transitions might find the 4-wheel version more stable. It is also important to note that while it excels at vacuuming debris, it does not have rotating brushes for scrubbing algae, so you will still need to maintain a regular brushing schedule for the waterline and walls.

Overall, the Hayward Poolvergnuegen is a premium suction-side cleaner that justifies its price through durability and intelligent design. It is particularly well-suited for pool owners using variable-speed pumps who want a quiet, effective cleaner that doesn't require the added electricity cost of a booster pump.

The Hayward Pool Vac XL W32025ADC is a specialized suction cleaner designed specifically for the unique textures of inground gunite and concrete pools. Unlike random-pattern cleaners, this model utilizes patented AquaPilot technology, which follows a pre-programmed steering path to ensure every inch of the pool floor and walls is scrubbed. This systematic approach is particularly effective at removing the fine dust and debris that often accumulate in the curves and coves of concrete pools.

Design-wise, the Pool Vac XL stands out for its simplicity and efficiency. It operates without the need for an expensive booster pump, instead drawing power directly from your pool's existing filtration system. The inclusion of a 40-foot hose and a wide vacuum inlet with a specialized wing design allows it to devour larger debris like leaves and twigs while maintaining a low profile that fits into tight corners.

One of the most significant benefits for homeowners is the maintenance-free aspect of the debris handling. Because it is a suction cleaner, it sends all captured dirt directly to your pool's primary filter, meaning there are no internal bags to empty or replace. Users frequently praise its silent operation, noting that it lacks the rhythmic 'hammering' or pulsating sound common in other suction models.

While the performance is generally high, users should be aware of the hose management. Depending on the pool shape and pump pressure, the hose can occasionally twist, requiring manual untangling to maintain full reach. Additionally, while the unit is built to last, the internal moving parts like the A-frame and turbine can be sensitive to large, hard objects if the suction is not properly regulated via the included gauge.

Final Verdict: For owners of gunite pools up to 20 x 40 feet, the Hayward Pool Vac XL is a reliable 'workhorse' that offers deep-cleaning capabilities without the high price tag of robotic alternatives. Its ability to clear walls and coves makes it a top choice for maintaining a pristine swimming environment with minimal manual brushing.

The Hayward AquaNaut 400 is a robust suction-side pool cleaner engineered specifically for larger in-ground pools. Its defining feature is the 4-wheel drive system, which provides the stability and power necessary to navigate deep ends and climb walls that often stall 2-wheel alternatives. By utilizing the pool's existing filtration system, it offers an automatic cleaning solution without the need for an expensive booster pump.

Performance is driven by the patented V-Flex turbine technology. Unlike fixed-vane turbines that can jam when encountering large debris, the V-Flex vanes self-adjust to allow larger items to pass through to the filtration system. This makes it particularly effective for pool owners dealing with heavy leaf fall or pine needles. The rugged tire treads further enhance its maneuverability, allowing it to roll over high-profile main drains without getting hung up.

In terms of coverage, the AquaNaut 400 uses pre-programmed internal steering sequences. This allows the cleaner to periodically reverse and turn, ensuring it doesn't just travel in circles but instead reaches every corner, step, and waterline. It is particularly well-suited for modern pool setups featuring variable-speed pumps, as its design maintains high suction efficiency even at lower flow rates.

While the unit is highly effective, users should pay close attention to the initial setup. Proper placement of the included hose sleeves and floats is critical; failure to balance the hose correctly can lead to the unit tipping onto its side. However, once dialed in, the AquaNaut 400 is a 'set and forget' tool that significantly reduces manual pool maintenance.

Final Verdict: The Hayward AquaNaut 400 is a top-tier choice for owners of large in-ground pools who want a reliable, clog-resistant cleaner. Its ability to handle large debris and navigate complex pool shapes makes it a worthwhile investment for maintaining a spotless swimming environment.

The Hayward W3900 Wanda the Whale is a specialized suction-side cleaner designed specifically for above-ground and on-ground pools. Unlike many generic cleaners, it features a unique turbine system that allows it to glide gently across the pool floor. This design not only ensures a quiet cleaning cycle but also acts as a circulation booster by pulling water from the bottom of the pool toward the surface.

Navigation is handled by Hayward's patented SmartDrive technology. This system is programmed to move the cleaner in a series of turns to ensure that no area of the pool floor is missed. The inclusion of a deluxe bumper ring is a thoughtful design touch, as it allows Wanda to bounce off walls and ladders without getting stuck or causing scuff marks on the pool liner.

Installation is one of the standout benefits of this model. It requires no tools and can be set up in under ten minutes by connecting the 32-foot hose directly to your pool's skimmer. Because it utilizes the existing filtration system's suction, there is no need for an expensive booster pump, making it a cost-effective alternative to high-end robotic cleaners.

While the performance is generally praised for its ability to handle everything from fine silt to small pebbles, users should be aware of the hose configuration. The included hose comes in sections, which some reviewers noted can separate if not firmly connected. Additionally, while the whale aesthetic is fun, the decorative tail is largely cosmetic and may detach during vigorous cleaning cycles.

Overall, Wanda the Whale is a reliable and charming workhorse for above-ground pool owners. It offers a significant upgrade over manual vacuuming with minimal maintenance requirements. As long as pool chemistry is maintained to prevent hardware corrosion and the hose sections are securely joined, this cleaner provides excellent value and a sparkling clean pool floor.
