The Zodiac Duo-X DX3000, DX4000 and DX4050 iQ share core cleaning technology, but they suit different pools. The main decisions are pool size and whether you want app connectivity.

Duo-X comparison

Model Pool fit Connectivity Best for
DX3000 Confirm current specifications No app feature claimed Core Duo-X features
DX4000 Up to 10 × 5m No app control Full coverage for standard pools
DX4050 iQ Up to 12 × 6m iAquaLink app Larger pools and connected control

Shared Duo-X cleaning technology

The range uses cyclonic suction and an active helix brush to loosen and collect debris. Dual-stage 150/60-micron filtration helps capture larger and finer material. A swivel reduces cable tangling, while the Lift System assists retrieval at the waterline.

DX3000: the core option

Choose the DX3000 when you want the fundamental Duo-X cleaning system without paying specifically for app connectivity. Confirm its current pool-size suitability before ordering.

DX4000: pools up to 10 × 5m

The DX4000 cleans the floor, walls and waterline, with a 15-metre cable, 4-litre dual-stage filter and three-motor drive. It is the middle choice when you need full coverage without iAquaLink control.

DX4050 iQ: larger pools and app control

The DX4050 iQ increases recommended pool size to 12 × 6 metres and uses an 18-metre cable. iAquaLink adds compatible phone-based monitoring and controls.

Before buying

  • Measure maximum pool length and width.
  • Confirm floor, wall and waterline requirements.
  • Check pool-surface compatibility.
  • Decide whether app control is worth the difference.
  • Allow for safe control-unit placement and cable storage.
