DOLPHIN FORMULA SERIES SPARE PARTS

Compatibility of Dolphin Formula Series replacement parts depends on the exact reference number printed on the identification label on the chassis or on the base of the robot. Maytronics divides the Formula range into three main variants with specific mechanical specifications:

• Formula 20: Designed for pool floors and coves, with a standard basket and 100-micron filtration.
• Formula 30: Features reinforced traction tracks, a front active-brush system, and multilayer filtration.
• Formula 35: Includes a floating cable with a Swivel system to prevent mechanical twisting during intensive cycles.

Check your unit’s serial number before ordering tracks, power supplies, or drive bearings to ensure a direct fit without any looseness.

A Dolphin Formula robot’s inability to climb is mainly caused by worn toothed tracks or a hardened active brush. Constant friction against the tile or liner wears down the tread on the traction belts, causing the pulleys to spin freely when the robot reaches the waterline.

First, check whether the tracks are cracked, excessively loose, or have lost their elasticity. If the rubber is smooth, replace the complete drive belt set and make sure the roller bearings turn smoothly. You should also clean the upper suction impeller: if dirt or wear on the impeller weakens the expelled water flow, the pool cleaner won’t generate the hydrodynamic thrust needed to stay attached to the wall.

The filter panels included with Dolphin Formula Series replacement parts should be replaced every two or three swimming seasons, depending on the debris load and the water’s chemical disinfection levels. Using flocculants or the continuous buildup of Saharan dust saturates the 50- and 100-micron fabric fibers, preventing normal water flow.

Replace the panel set if you notice cracks in the plastic frame corners or if the basket remains darkly discolored after pressure washing. Using clogged filters overheats the internal motor by forcing the pump and reduces suction in the pool.

Yes, the Easy-Clean basket on Dolphin Formula Series robots accepts interchangeable panels of different densities without requiring structural modifications to the upper compartment. Users can switch between two filtration configurations:

• Spring panels (100 microns): suitable for opening the pool for the season, large leaves, insects, and dense debris.
• Ultra-fine filters (50 microns): designed for suspended dust, microscopic dead algae, and fine sand particles.

Installing the ultra-fine panels improves water clarity and reduces the workload on the facility’s main filtration system without compromising the robot’s hydraulic flow.

The fundamental technical difference lies in the rotation speed and direct drive transmission against the surface. Conventional rollers turn at the same rate as the tracks through simple perimeter drag, while the front active brush rotates at twice the robot’s travel speed.

This intensive rotary action actively scrubs biofilm, embedded bacteria, and microalgae from the pool floor. When purchasing brush replacements for the Formula Series, make sure to choose a synthetic compound compatible with your pool lining (PVC, fiberglass, or glazed ceramic) to prevent premature slipping when climbing.

Continuous coiling of the floating cable is usually caused by a jammed Swivel device or heat-related deformation of the outer polyurethane coating. If the cable has surface cuts, pronounced stiffness, or the power supply reports an electrical continuity fault, the entire cable must be replaced to ensure the low-voltage connections remain watertight.

To extend the life of the new cable, lay the entire cable out in the sun before each filtering cycle to remove its coiled memory, and unplug the two-pin plug by always pulling on the threaded connector, never on the cable itself.

Preventive maintenance at the end of the swimming season extends the service life of Dolphin Formula Series spare parts and prevents corrosion of mechanical seals:

• Wash the filter basket with fresh, chlorine-free water and dry it in the shade to protect the fabric mesh.
• Remove any hair and fibers caught in the drive pulleys and on the front active brush shaft.
• Store the elastic tracks without placing the equipment’s weight directly on them, using the storage stand or positioning the robot upside down.

Store the complete unit and its power supply in a dry place, protected from direct sunlight and winter frost.
