Buying guide

What to look for

Assessing Pool Size Compatibility

The most important factor when selecting a robotic cleaner is ensuring it is rated for your pool's specific dimensions. Many models, such as the Proteus DX series, have strict limits on pool length. Purchasing a unit that is undersized for your pool will result in incomplete cleaning cycles and excessive wear on the motor. Always verify the maximum length stated in the product specifications. If your pool is at the upper limit, consider upgrading to a more robust model to ensure full coverage. Never assume a model will work for a larger pool than specified, as the internal navigation and cable length are calibrated for specific surface areas and depths.

Evaluating Filtration Requirements

Consider the type of debris common in your area when choosing a filter system. If your pool is surrounded by trees or experiences high levels of fine sediment, look for models that support ultra-fine filtration baskets. While standard baskets are effective for leaves and larger debris, they may allow fine silt to pass through. Some models offer top-load access, which simplifies the cleaning process significantly. Check if the model you are interested in allows for interchangeable filter types, as this provides flexibility to adapt to changing pool conditions throughout the year. Investing in the right filtration setup from the start will save you time and improve overall water clarity.

Reviewing Wall Climbing Capabilities

Not all robotic cleaners are designed to scrub walls or the waterline. If your pool has significant buildup on the sides, prioritize models that explicitly mention wall-climbing and waterline scrubbing features. These units use specialized brushes and navigation algorithms to maintain contact with vertical surfaces. Be aware that wall climbing requires the pool surface to be in good condition; if your pool has a very slippery surface or excessive algae, even the best wall-climbing robot may struggle. Check if the model includes an active scrubber brush, which is essential for dislodging stubborn grime that passive suction alone cannot remove during the cleaning process.

Understanding Smart Connectivity Features

Wi-Fi enabled cleaners offer the convenience of smartphone control, allowing you to start cycles or set schedules remotely. This is a significant advantage for busy owners, but it requires a stable Wi-Fi signal near the pool area. Before purchasing, verify that your pool location has adequate connectivity. If you prefer a simpler, plug-and-play experience, a non-connected model may be more reliable and easier to set up. Think about whether the added complexity of an app is necessary for your lifestyle or if a standard, button-operated cleaner will suffice for your routine maintenance needs. Connectivity should be viewed as a convenience feature rather than a requirement for effective cleaning.

Checking Surface Compatibility Factors

Robotic cleaners are generally designed for specific pool surfaces, such as concrete, vinyl, or fiberglass. Before finalizing your purchase, confirm that the model is compatible with your pool's finish. Some brushes are optimized for smooth surfaces, while others provide better traction on rougher materials. Using an incompatible cleaner can result in poor traction, ineffective scrubbing, or even surface damage. If your pool has unique features like sun-ledges or beach entries, ensure the cleaner's navigation system is capable of handling these transitions. Always check the manufacturer's compatibility list or contact support if you are unsure whether a specific model is suitable for your pool's unique construction materials and design.

Considering Long-Term Ownership Costs

Beyond the initial purchase price, consider the long-term costs of owning a robotic pool cleaner. This includes the price of replacement parts like brushes, tracks, and filter baskets, which will eventually need to be swapped out due to wear. Look for models with easily accessible parts and clear maintenance requirements. Some units may require more frequent filter replacements depending on your pool environment. Additionally, consider the availability of authorized service centers in your area. While cheaper models may seem attractive, they can become costly if parts are difficult to source or if the unit lacks the durability for long-term use. Factor these ongoing expenses into your total budget before making a final decision.

Verifying Warranty and Support

A reliable warranty provides peace of mind for an investment in pool equipment. Before buying, carefully read the warranty terms, including what is covered and for how long. Pay attention to whether the warranty applies to the motor, the power supply, or only specific components. Understand the procedure for making a claim, as some manufacturers require shipping the entire unit to a service center. Check the availability of customer support and the ease of accessing technical documentation. A company with a strong reputation for customer service and readily available spare parts is often worth a slightly higher initial investment, as it ensures your pool cleaner remains functional for many years.

Ownership guide

Setup, use, and maintenance

Filter Basket Cleaning Routine

Regularly removing and rinsing the filter basket is the most critical task for maintaining your robotic cleaner's suction power. After each cycle, open the top-load compartment, extract the basket, and spray it thoroughly with a garden hose to dislodge trapped debris. Avoid using high-pressure washers, which can damage the fine mesh. If you are using an ultra-fine basket, pay extra attention to the corners where silt accumulates. Always allow the filter to air dry completely before reinserting it into the unit.

Inspecting Scrubbing Brushes

The active scrubbing brushes are responsible for dislodging algae and dirt from pool surfaces. Periodically inspect these brushes for signs of wear, such as fraying or flattening of the bristles. If the brushes become too worn, they will lose their effectiveness in cleaning the floor and walls. Check for debris like twigs or hair that may have become tangled in the brush rollers, as these can impede rotation.

Managing Power Supply Safety

The power supply unit is the heart of your robotic cleaner and must be handled with extreme care. Always ensure the power supply is kept in a dry, shaded area, away from direct sunlight and potential water splashes. Never operate the unit if the power cord appears frayed or damaged; contact a professional for repairs if you notice any electrical issues. During the off-season or long periods of non-use, disconnect the power supply and store it in a cool, dry environment. Ensure that all electrical connections are clean and free of corrosion.

Cable Management and Storage

The floating cable is prone to tangling if not managed correctly during storage. After each cleaning cycle, carefully coil the cable loosely, ensuring there are no sharp bends or kinks that could damage the internal wiring. Avoid wrapping the cable tightly around the cleaner itself, as this can cause stress on the connection points. Store the cleaner in a location that is protected from extreme temperatures and direct UV exposure, which can degrade the plastic housing and the cable insulation over time.

Troubleshooting Operational Boundaries

If your robotic cleaner stops mid-cycle or fails to climb walls, first check for obstructions in the intake or debris in the filter basket. Ensure that the water chemistry is balanced, as high algae levels can make pool surfaces slippery, preventing the unit from gaining traction. If the cleaner continues to struggle, inspect the tracks or wheels for debris. Always consult the troubleshooting section of your manual before attempting any internal repairs. If the issue persists, do not attempt to open the motor housing, as this will void your warranty.

FAQ

Robotic Pool Cleaners — FAQ

Can I use the Dolphin S50 in a saltwater pool?

Most robotic cleaners, including the Dolphin S50, are designed to operate in saltwater pools, provided the salt concentration is within the recommended range for the pool. However, it is essential to check your specific manual to confirm compatibility with your pool's salinity levels. Over time, salt can be corrosive to internal components, so it is crucial to rinse the cleaner with fresh water after every use to remove any salt residue. This simple step significantly extends the lifespan of your unit and prevents premature damage to the motor and electrical connections, ensuring reliable performance throughout the swimming season.

How often should I clean the filter basket?

For optimal performance, the filter basket should be cleaned after every single use. If you wait until the basket is visibly full, the suction power of the cleaner will decrease, and the unit may struggle to pick up debris. In pools with heavy leaf loads or fine sediment, you may even need to empty the basket mid-cycle. Regular cleaning prevents the motor from overworking and helps maintain consistent water flow. Always rinse the basket thoroughly with a garden hose and ensure it is completely dry before reinserting it into the cleaner. This habit is the most effective way to maintain your cleaner's efficiency.

Is it safe to leave the cleaner in the pool?

It is generally recommended to remove the robotic cleaner from the pool after each cleaning cycle. Constant exposure to pool chemicals, such as chlorine, can degrade the plastic housing, the brushes, and the cable insulation over time. Additionally, leaving the unit in the water can lead to algae growth on the cleaner itself, which is difficult to remove. Storing the cleaner in a cool, dry, and shaded area when not in use protects it from harsh UV rays and chemical exposure. By removing the unit, you also keep it out of the way of swimmers and prevent accidental damage to the equipment.

What should I do if the cleaner gets stuck?

If your cleaner stops moving or gets stuck, first ensure that the power supply is on and the cable is not tangled. Check for large debris, such as sticks or toys, that might be wedged in the intake or brushes. Sometimes, the cleaner may get stuck on pool features like stairs or drains; in these cases, simply repositioning the unit can resolve the issue.

Can I use the cleaner while people are swimming?

No, you should never operate your robotic pool cleaner while people are in the pool. The cleaner is an electrical device, and although it is designed for underwater use, there is always a risk of entanglement with the power cable or accidental injury from the moving parts. For safety reasons, always remove the cleaner from the pool before allowing anyone to swim. This ensures a safe environment for swimmers and prevents the cleaner from being damaged by rough play or accidental impacts. Always follow the safety guidelines provided in your owner's manual regarding the operation of the equipment in the presence of swimmers.

How do I know if my pool surface is compatible?

Most robotic cleaners are compatible with standard pool surfaces like concrete, vinyl, and fiberglass. However, the effectiveness of the cleaner can vary depending on the surface texture. For example, a cleaner that works well on smooth tile might struggle with traction on a rough concrete surface. Before purchasing, check the product specifications to see if your pool surface is explicitly listed as compatible.

What is the benefit of an ultra-fine filter?

An ultra-fine filter basket is designed to capture much smaller particles than a standard mesh filter. While a standard filter is excellent for leaves, twigs, and larger debris, it will often allow fine silt, sand, and dust to pass right through and back into the pool. An ultra-fine filter traps these tiny particles, resulting in significantly clearer water.

Does the cleaner require a booster pump?

No, robotic pool cleaners like the Dolphin S50 and Proteus series do not require a booster pump. They are self-contained units that operate independently of your pool's existing filtration system. The cleaner uses its own internal motor to create suction and move around the pool, which makes it much more energy-efficient than pressure-side cleaners that rely on the pool's pump. This independent operation also means you do not need to worry about plumbing connections or additional equipment. Simply plug the power supply into a GFCI-protected outlet, drop the cleaner into the pool, and it is ready to perform its cleaning cycle automatically.
