DOLPHIN AQUARIUS SERIES SPARE PARTS

To check whether Dolphin Acuarius Series replacement parts are compatible, use the serial number and exact model listed on the machine’s identification label. This technical sticker is usually located inside the chassis or on the side of the plastic housing.

Models in this range, such as the Aquarius R4 and Aquarius R5, share components in the drive unit but may differ in the filter basket configuration or inner panels. Checking the official exploded-parts diagram helps prevent buying parts that do not fit the shafts or mounts of your electric pool cleaner.

The usual cause of lost grip on walls is wear from friction on the drive tracks or brush rings. With constant contact and the water’s chemical cycles, the rubber loses its elasticity and tread, reducing mechanical grip.

Check the following parts to restore the unit’s traction:

• Side toothed tracks: replace them if they are cracked or loose on the guide wheels.
• Active or combination brushes: replace the PVC bands when the bristles lose their original texture.
• Drive belts: make sure they transmit the motor’s rotation without slipping on the drive roller.

Replacing these components restores full mobility to the pool cleaner during each cleaning cycle.

Ultrafine filtration panels trap microscopic particles as small as 50 microns, while spring filters are designed to retain bulky debris such as leaves and branches without clogging immediately. The right choice depends on the time of year and how cloudy the water is.

At the start of the season or after severe storms, spring filter panels can capture coarse debris without overloading the suction turbine. The ultrafine filters are then installed to trap fine dust and suspended particles, improving the clarity of the pool floor.

Replacing the floating cable with a unit featuring a rotating swivel device permanently eliminates knots and structural twists during operation. The swivel mechanism rotates 360 degrees on its own axis, dissipating the accumulated tension generated by the robot as it makes successive turns.

A stiff or excessively twisted cable causes the pool cleaner to lose perimeter coverage and shortens its straight-line travel. Installing a new floating cable assembly with a swivel restores the programmed range of motion and protects the power supply connection from sudden tugs.

Brushes and toothed tracks usually need replacing after two to three seasons of regular use, depending on the number of hours used per week and the roughness of the pool lining. In pools with tile or abrasive surfaces, friction accelerates wear on the synthetic material.

Proper preventive maintenance requires checking belt tension and tread depth twice a year. Buying original Dolphin Serie Acuarius replacement parts preserves the millimeter-level tolerances that ensure the drive motor does not have to work under strain.

The robot stopping prematurely may be due to either thermal protection in the motor block or a voltage drop in the power supply transformer. To isolate the cause of the fault, it is essential to first rule out visible mechanical blockages in the moving parts.

Follow these inspection steps before replacing components:

• Remove the upper impeller and check for hair or threads blocking the rotor.
• Check that the tracks and axles turn freely when moved manually out of the water.
• Inspect the cable connector to make sure there are no corroded or damp pins.

If resistance persists in the drive train, replacing the affected bearings or rollers will restore normal electrical flow.

The vast majority of Dolphin Serie Acuarius replacement parts are designed for users to install directly, without requiring special tools or complex technical knowledge. Components such as filter panels, lamellar brushes, and drive tracks are assembled using pressure clips and quick guides.

For work inside the motor block or opening watertight chambers, it is recommended to check the tightening torque of the O-rings. This ensures complete watertightness and prevents moisture from entering the electronics.
