A suction-side hydraulic pool cleaner requires a filtration pump with a minimum power of 0.5 to 0.75 HP to operate with constant traction. The Zodiac MX8 automatic pool cleaner requires at least 0.75 HP to move its toothed turbines and climb walls, while diaphragm models work properly with 0.5 HP on flat floors.

For pools with steep slopes and complex corners, the technical recommendation is a turbine system rather than a flat membrane disc. The mechanical differences determine its ability to move over slopes:

• The Zodiac T5 Duo automatic pool cleaner features a dual-material flexible disc with DiaCyclone diaphragm technology, ideal for flat floors or gradual, continuous slopes.
• The MX8 model’s X-Drive turbine transmits traction through mechanical tracks, ensuring grip on steep drops and abrupt changes in slope.

Assess the profile of your pool floor before choosing your suction equipment to prevent blockages during the regular filtration cycle.

The cyclonic retention accessory attaches directly between the first hose connected to the suction outlet and the rest of the floating hose. By inserting the Zodiac Cyclonic™ Leaf Catcher leaf pre-filter, large plant debris is trapped in a transparent chamber by the vortex current. This setup prevents large leaves from reaching the pump basket or clogging the main filter sand, maintaining a constant suction flow without pressure loss.

For pools of up to 20 cubic metres without an external heat source, installing a compact electric heater directly in the line is the most efficient option. The unit Zodiac Red line 3 electric heater - Ref. W40DE3 supplies 3 kW of power with an internal corrosion-resistant titanium heating element. This single-phase unit includes a digital control thermostat with overheat shutoff and a flow switch that activates only when the filtration pump delivers a continuous flow.

The difference lies in the primary energy source used to raise the pool water temperature. The electric heater generates heat independently using an internal titanium heating element powered by the home's mains electricity. In contrast, a heat exchanger such as the Heat Line series uses the primary hot-water circuit from a domestic boiler or heat pump to transfer energy to the pool's secondary circuit without the two fluids coming into contact.

Connecting to a skimmer is entirely feasible using the universal conical adapter and the flow regulator valve included in the original package. To ensure the hydraulic system operates correctly in 2026, follow these three technical adjustment steps:

• Insert the adapter into the skimmer base, ensuring a tight seal with no looseness.
• Connect the Twist Lock hose sections, purging any air accumulated in the line before turning on the filtration system.
• Adjust the flow valve to calibrate the wheel rotations or diaphragm pulses according to the manufacturer's official manual.

This procedure protects the motor against cavitation and prevents air pockets in the suction pipe.

Flow is checked by measuring the wheel rotation time or diaphragm pulse rate using the official flow tester supplied with the unit. If the travel speed is below the revolutions per minute set by the manufacturer, you must partially close the main drain valves and secondary skimmers to concentrate the hydraulic suction at the cleaner connection.
