🌀 Cyclonic Suction Technology

How It Works

Zodiac’s patented cyclonic suction technology is the heart of the CNX 25’s cleaning performance. Unlike conventional pool cleaners that can lose suction as the filter fills, cyclonic action keeps debris suspended inside the filter canister, preventing blockages and maintaining consistent, powerful suction throughout the entire cleaning cycle.

The Cyclonic Advantage

Feature	Benefit
🌀 Debris Suspension	Keeps particles moving to prevent filter clogging
💪 Consistent Suction	Maintains strong cleaning power throughout cycle
🧹 Efficient Collection	Captures more debris per cleaning session
⏱️ Longer Cycles	Extended cleaning without interruption

💧 Dual-Stage Progressive Filtration

The CNX 25 comes equipped with a sophisticated dual-stage filtration system that captures debris of all sizes:

Filter Stage	Mesh Size	Captures
Standard Filter	150 µm	Leaves, twigs, insects, large debris
Fine Filter	60 µm	Sand, dust, pollen, fine particles

Filter Specifications

Specification	Value
Total Filter Capacity	4 litres
Filter Surface Area	1,066 cm²
Access Type	Top-access with transparent lid
Inspection	Visual through transparent window

💡 Tip: For heavily soiled pools, run several cycles with just the 150µm filter first to remove larger debris before fitting the fine 60µm filter.

🔄 Cleaning Cycles

The CNX 25 offers two preset cleaning programmes to suit your needs:

Cycle	Coverage	Description
Floor Only	Pool floor	Quick clean focusing on bottom debris
Full Cycle	Floor + Walls + Waterline	Complete pool cleaning

Simple Operation

The CNX 25 is designed for plug-and-play convenience:

1. Roll out the 15m cable alongside the pool
2. Immerse the cleaner vertically and release air bubbles
3. Connect the floating cable to the control box
4. Plug into mains power (30mA RCD protected)
5. Select your cleaning cycle and press start

No app, no Wi-Fi, no complicated setup – just simple, effective pool cleaning.
