Buying Guide

Key Features to Consider

When selecting a Dolphin inground pool cleaner, prioritize the filtration system and navigation technology. Dual-filter baskets are essential for capturing both fine debris and large leaves, ensuring comprehensive water clarity. Additionally, look for models equipped with CleverClean or SmartNav software, which systematically scan the pool to avoid missed spots, and always verify the cable length exceeds your pool’s dimensions to guarantee full coverage.

Budget Recommendations

Entry-level models, typically priced between $700 and $900, effectively clean the floor and are ideal for standard maintenance. Mid-range units ($900–$1,300) often include wall-climbing capabilities and Bluetooth connectivity for remote control. For ultimate convenience, premium models exceeding $1,300 offer advanced scrubbing brushes and large capacity filters, making them a worthwhile investment for larger or complex pool shapes.

Common Pitfalls to Avoid

Avoid purchasing a cleaner solely based on the lowest price point, as budget models may lack the necessary power to climb walls or navigate obstacles efficiently. A frequent mistake is ignoring the cable length; ensure the cord is long enough to reach the furthest point of your pool from the power supply. Finally, always check for manufacturer warranty exclusions regarding unauthorized sellers to ensure your investment remains protected.

Frequently Asked Questions

How long does it take for a Dolphin cleaner to clean an inground pool?

Most Dolphin robotic pool cleaners have a standard cleaning cycle that lasts between 1.5 to 2 hours. Many models also offer 'Quick Clean' settings for maintenance or extended cycles for larger or heavily soiled pools.

Do I need to leave my pool pump running for the Dolphin to work?

No, you do not. Dolphin cleaners are robotic and operate independently of your pool's main filtration system. They have their own internal motors and filtration baskets, which saves energy and reduces wear and tear on your main pool pump.

Will a Dolphin cleaner climb the walls and clean the waterline?

Yes, most Dolphin models designed for inground pools feature advanced navigation systems and scrubbing brushes that allow them to climb vertical walls and clean the waterline tile, helping to remove grime and calcium deposits.

How often should I clean the filter cartridge or basket?

It is recommended to remove and rinse the filter basket or cartridge after every cleaning cycle. This ensures optimal suction performance and prevents debris from clogging the internal mechanics of the robot.

What happens if the Dolphin cleaner gets stuck or tangled in cables?

Modern Dolphin cleaners often come with tangle-free swivel cables to prevent knots. If the unit gets stuck, it is usually due to a physical obstruction like a drain or a sharp corner. Moving the power supply box or using a cable float can often resolve these issues.
