10 Best Ground Pool Cleaners 2026 in the United States

The Dolphin Nautilus CC Automatic Robotic Pool Vacuum Cleaner is an efficient and user-friendly option for both above-ground and in-ground pools up to 33 feet in length. One of its standout features is the wall-climbing capability, allowing it to clean various pool surfaces effectively. However, it does not clean the waterline, which might be a drawback for some users. The active scrubbing brush is another strong point, as it ensures thorough cleaning with minimal manual effort and is gentle on pool surfaces while being tough on debris.

Maintenance is simplified with the top-load filter basket, making debris removal straightforward and keeping the pool water crystal clear. The plug-and-play functionality means you can easily operate it by just plugging in, dropping it into the pool, and powering it on, with a full cleaning cycle completed in about 2 hours. The product is crafted from durable plastic and benefits from the Dolphin brand's 40-year legacy of reliable, cost-saving pool cleaners.

It is lightweight at 14 pounds, making it easy to handle and store. The cleaner is energy efficient, operates on 230 volts, and does not require assembly, which adds to its convenience. Despite these strengths, the cleaner’s inability to address the waterline might necessitate additional manual cleaning. The limited warranty might also be a consideration for some buyers.

The Dolphin Nautilus Pool Up Automatic Robotic Pool Vacuum Cleaner is designed for both above-ground and in-ground pools up to 26 feet in length. It's a versatile cleaner that handles a variety of pool shapes and surfaces effectively, making it suitable for small to medium-sized pools. One of its standout features is the wall-scrubbing capability, ensuring comprehensive cleaning from floor to walls. The active scrubbing brush is efficient in removing debris while being gentle on pool surfaces, reducing the need for manual cleaning efforts.

The plug-and-play system offers ease of use; simply drop the cleaner into the pool and let it work, providing a spotless pool in about two hours. This model is known for energy efficiency, saving costs on electricity while delivering robust cleaning performance. Durability is a highlight, with a legacy of over 40 years backing its performance and reliability, and it comes with a limited warranty for added peace of mind.

However, at 28.5 pounds, it is relatively heavy, which might pose a challenge during initial setup or removal from the pool. Additionally, while it has a lithium-ion battery, it still requires an AC power source to operate, limiting its mobility. This cleaner is ideal for pool owners looking for an efficient, easy-to-use, and reliable pool maintenance solution.

The Zodiac MX6 Automatic Suction-Side Pool Cleaner is a solid choice for in-ground pools, particularly those on the smaller side. Its powerful vacuum and Cyclonic Turbine technology ensure excellent suction and efficient cleaning, including climbing walls and reaching the waterline. This makes it versatile for different pool shapes and surfaces like concrete, vinyl, fiberglass, and tile.

The compact design is a plus for storage and handling, especially in smaller pools or areas with limited space. One of its standout features is the low-flow design, which is ideal for pools with 2-speed or variable-speed pumps, helping to reduce energy consumption. The X-Drive Navigation system ensures thorough and systematic cleaning, covering the pool floor, walls, and waterline effectively.

The package includes a 32' Twist Lock Hose and a Flow Regulator Valve, adding to its ease of use. However, the cleaner is made of plastic, which may raise some concerns about its long-term durability. While the product seems robust, potential buyers should consider the warranty details to ensure they are covered for any possible wear and tear. In summary, the Zodiac MX6 is energy-efficient, easy to use, and performs well on various pool surfaces, making it a good option for smaller in-ground pools.
