Polaris Polaris VRX iQ+ Robotic Pool Cleaner with iAquaLink MECH-STUCK Error Fix: Cleaner Gets Stuck — Drains, Steps, Corners

Error code MECH-STUCK on the Polaris Polaris VRX iQ+ Robotic Pool Cleaner with iAquaLink means: Cleaner Gets Stuck — Drains, Steps, Corners. The robotic cleaner gets stuck on main drains, ladders, steps, or in pool corners: (1) Main drain covers — some drain cover designs create suction that traps the cleaner. Install a VGB-compliant drain cover with a domed shape that allows the cleaner to pass over. (2) Steps and benches — the cleaner may drive onto a step and be unable to back off. Some models have an anti-stuck algorithm that reverses the cleaner, but obstacles can still trap it. (3) Ladders — the cleaner can wedge between ladder rails. Consider removing the ladder or installing a cleaner guard. (4) Corners — tight 90° corners can trap the cleaner, especially if the cable is tangled. (5) Cable management — ensure the cable is not wrapped around pool features before starting a cycle. The PSU will show a solid red LED (LED-RED-SOLID) when the cleaner stalls.
