DOLPHIN XT SERIES

The Dolphin XT Series is designed to effectively clean residential pools up to 12 meters long. Its 15- to 18-meter power cable with a swivel system prevents twisting and allows it to cover in-ground or above-ground pools with rigid walls.

The unit operates at a constant suction flow rate of 15 cubic meters per hour and adapts to various pool types:

• Rectangular or freeform pools up to 12x6 meters.
• Flat bottoms, gentle slopes, or hopper-style drops with à carrelage, liner, or polyester finishes.
• Beach areas and Roman-entry steps with gradual access.

Its hydrodynamic design ensures a firm grip without relying on the main filtration pump.

The Dolphin XT Series features an active front brush that spins at twice the speed of the pool cleaner's drive system to remove embedded biofilm. This intensive mechanical action loosens organic and mineral buildup from the à carrelage joints before vacuuming it into the internal compartment.

To prevent recurrences during the cycle, it is advisable to monitor chemical levels using a Scuba II pool photometer to ensure balanced chlorine and pH levels. The combination of tracked traction and navigation software makes it easier to climb vertically and steadily up to the skimmer level.

The XT series replaces conventional fabric bags with a top-access Easy-Clean basket featuring modular 50-micron and 100-micron panels. This setup lets you switch between ultrafine filtration for dust in summer and coarse filtration for organic debris after spring storms.

Unlike manual pool cleaners connected to the suction system, which overload the sand filter, the robot traps impurities independently. This reduces how often the filtration system needs backwashing, saving hundreds of liters of water each season.

Maytronics pool cleaners run on very low-voltage direct current through a sealed transformer with IP54 insulation, which converts household current to 24 volts. This specification ensures complete electrical safety in the water.

However, European safety regulations recommend removing the equipment and its cable during swimming hours to eliminate the risk of tripping or entanglement. If you need to reinforce passive protection around the pool when the robot has finished its task, an Aqualarm Pool Alarm provides an immediate acoustic alert if anyone accidentally enters the water unsupervised.

The equipment’s preventive maintenance routine takes less than five minutes after the two-hour cycle automatically ends. Following these guidelines extends the service life of the mechanical components and sealed bearings:

• Remove the top basket by pressing the front latch and rinse the panels with a hose without excessive pressure.
• Visually inspect the upper impeller to make sure no hair or twigs are wrapped around it.
• Unwind the floating cable and store it extended in the shade, avoiding tight bends.
• Store the robot on a rigid stand or cart to prevent the rubber tracks from deforming.

Keeping the tracks off the hot ground preserves the traction needed to climb walls.

Fine particles escaping during cleaning can be addressed by installing the 50-micron panels in the Easy-Clean basket and checking that the water is free of colloidal turbidity. When microscopic particles are smaller than 30 microns, they remain suspended due to the suction movement.

In these cases of cloudy water, applying a pre-treatment with ULTRA CLEAR Super Clarifier, 1 L. PM-643. Piscimar. clumps suspended impurities into dense flakes. Once they settle on the bottom, the Dolphin cleanly vacuums them up on its next pass without returning residue to the water column.

A Dolphin XT Series pool cleaner consumes approximately 150 watts per hour, compared with the more than 750 watts required by the 1 HP circulation pump needed to operate a hydraulic pool cleaner. This difference reduces electricity costs by more than 75% during the peak-use season.

In addition to direct consumption, Maytronics’ electric model protects the main filter sand and the pump’s pre-filter by trapping twigs and gravel in its internal basket. The initial investment pays for itself through reduced wear on the filtration motor and fewer water top-ups.
