Robotic pool cleaners, particularly rechargeable, battery-powered cordless models, are revolutionizing pool maintenance. Although they offer ease and mobility, these models have both advantages and disadvantages, as found in a comprehensive test of over 40 pool robots.
Cordless pool cleaners provide convenience by eliminating power cords, enhancing safety and ease of use. However, they require frequent user intervention, often twice a day for recharging, which can detract from their automation benefits. Their dependence on rechargeable batteries makes them less hands-off compared to corded models.
Cordless models typically have less powerful motors than corded cleaners, impacting their cleaning efficiency, especially with challenging debris and pool shapes. Additionally, their batteries often require frequent recharging and tend to degrade over time, leading to shorter operational times and the added cost of battery replacement.
While they offer the benefit of cord-free operation, cordless pool cleaners also come with challenges such as constant attention, lower suction power, limited battery life, and the ongoing cost of battery replacements. These limitations suggest that they might not be ready for real-world use, with hopes for future improvements in battery technology.
When selecting a cordless pool cleaner, consider factors like rechargeable battery life, suction power, adaptability to different pool shapes, ability to clean vertical surfaces, build quality, ease of maintenance, smart features, and robust warranty and support. The Maytronics Dolphin models are noted for their build quality and warranty.
In conclusion, the choice of a cordless robotic pool cleaner should balance technological capabilities, user experience, and value. The aim is to ensure a pristine, hassle-free pool environment, guided by key factors like endurance, cleaning efficiency, build durability, and user-friendly operation and support.
