Our take

Zodiac CNX-Li 52 iQ

Certain CNX-Li 52 iQ batches are covered by Zodiac’s battery recall. Check the exact serial number.

What the evidence supports

The manufacturer provides a free remedy for affected units.

Limitations and uncertainties

Battery water intrusion can cause overheating; the notice does not cover every unit.

Best for

Pools that need cordless floor, wall and waterline cleaning.

Skip it if

Buyers who need a robot that is available to buy immediately.

What stands out

Cordless floor, wall and waterline cleaning
iAquaLink connectivity

What the evidence shows

For the CNX-Li 52 iQ, the most consequential verified ownership information is a battery recall affecting particular production batches. Exact-unit eligibility matters more than general brand feedback.

Check the specific unit

Zodiac names the CNX-Li 52 iQ in its recall notice. Water entering the battery can lead to overheating in affected units. The manufacturer provides a serial-number checker; the notice does not mean every CNX-Li 52 iQ is affected. Follow the official instructions for the result returned for your robot.

What the remedy covers

The recall programme describes free battery-block replacement, including collection and return. This is a concrete support process for affected units, not evidence of normal cleaning quality or a prediction that an unaffected robot will fail.

Cleaning feedback still needs depth

The sources reviewed do not establish a dependable exact-model picture of coverage, filter cleaning or battery life after several seasons. Reports about other cordless Zodiac models should not fill those gaps.

Also consider · Beatbot AquaSense 2

Why consider it: Owners praise floor, wall and waterline coverage and its ability to handle curved or bean-shaped pools.

The compromise: It is expensive, and owners still need to run an extra cycle when fresh debris falls in after a clean.

Beatbot · Released 2025

AquaSense 2

A very capable cordless cleaner for shaped pools. Owner feedback is especially positive on coverage and navigation in pools where cheaper cordless robots struggle.

International listing · EUR€1,099.00

Also consider · BWT ES 800

Why consider it: It cleans floor, walls and waterline, weighs under 6kg and offers three app-selectable cycles plus an anti-tangle cable system.

The compromise: Independent reliability and cleaning evidence is very thin, and it still carries the normal inconvenience of a power cable.

BWT · Year not confirmed

ES 800

A lightweight corded cleaner with sensible app control and a proven conventional design. It looks easy to live with, but we found almost no independent owner evidence, so we would not choose it over a better-documented Dolphin at the same price.

Also consider · BWT ES Echo

Why consider it: Owners like the light cordless setup, long battery life, straightforward app control and solid floor and wall cleaning for normal maintenance.

The compromise: Independent testing found weaker corner pickup, some dirt being stirred or released back into the pool, and filtration that is not as fine as premium rivals.

BWT · Year not confirmed

ES Echo

A practical cordless pool cleaner with very good runtime and easy handling, but not a perfectionist cleaner. Testing and owner reviews agree that it removes most everyday debris well; corners, ultra-fine dirt and some debris spill-back on removal are the main compromises.
