DOLPHIN SPRINT SERIES

The Dolphin Sprint Series pool-cleaning robot is designed for use in residential in-ground or above-ground pools up to 10 meters long. Its compact chassis and track-drive system let it move across flat floors, gentle slopes, and standard changes in elevation. It works consistently on common surfaces such as polished tile, PVC liner, fiberglass, and painted concrete. Its maneuverability depends on a 15-meter floating cable that prevents tangling during the programmed cleaning cycle, ensuring consistent performance regardless of the pool’s perimeter finish.

Fine particles on plastic surfaces are effectively collected thanks to the active front brush and its calibrated speed. The robot moves forward while the brush spins at twice the robot’s speed, dislodging debris and algae and directing them straight to the main suction inlet.

Compared with other basic models, it offers specific mechanical advantages:

• Moves steadily without slipping on PVC, thanks to its toothed traction tracks.
• Immediately collects fine sand in its internal basket without releasing dust back into the water.
• Dynamic braking prevents loss of traction as the robot moves from the slope to the floor.

This setup prevents the drive wheels from jamming and maintains stability throughout the cleaning session.

The Dolphin Sprint Series robot’s standard cleaning cycle lasts a fixed 2 hours. During this time, the control unit calculates the pool floor area and performs a thorough algorithmic scan. After 120 minutes of operation, the device automatically shuts off to prevent unnecessary mechanical wear and reduce electricity consumption. It requires no supervision, so simply submerge the unit, plug the power supply into a household outlet, and press the start button.

The filter tank is cleaned entirely from the top of the chassis without turning the device over. Pressing a button on the housing releases the top cover, allowing you to remove the basket without dismantling the turbines or touching the trapped debris. To maintain optimal suction, remove the top-loading module, rinse it with a garden hose at low pressure to dislodge leaves and impurities, then reinsert it until you hear the locking click. This preventive maintenance routine extends the motor’s service life and preserves its full suction capacity.

An electric robot like those in the Sprint range operates as an autonomous cleaning unit with its own suction motor and integrated filtration. By contrast, a suction-side pool cleaner depends entirely on the power of the pool’s circulation pump and sends debris directly to the pump’s prefilter or sand filter tank. While the automatic Dolphin pool cleaner does not clog the filter bed in the filtration system, options connected to the suction outlet reduce the overall water flow in the technical circuit and require much more frequent filter backwashing to prevent pressure loss.

The mechanical components of the Dolphin Sprint Series can withstand standard salt chlorination concentrations of up to 4,000 to 5,000 ppm. The motor unit’s watertight seals and polypropylene housings isolate the internal circuits to prevent chemical corrosion. To protect the tracks’ rubber and the turbine shaft, we recommend rinsing the unit with tap water after removing it from the pool and monitoring the chemical levels. Make sure the pH stays between 7.2 and 7.6 and the water temperature is above 12 °C before starting the automatic cleaning program.

This specific model focuses its hydraulic performance exclusively on intensive cleaning of the floor and the cove. The Sprint range’s design prioritizes vacuuming heavy sediment from the floor while using little energy, foregoing the additional buoyancy required for the waterline cleaning range. This technical specialization offers the following operational advantages:

• Maximum suction power focused on the floor, where 90% of physical debris settles.
• Less wear on the drive belts and mechanical seals thanks to the absence of vertical strain.
• Faster cleaning passes over rectangular or oval floors without pauses to climb.

If the pool accumulates grease along the upper perimeter, it’s best to supplement the task with manual cleaning or a higher-end model specifically designed for edges.
