■ The catch — co-equal billing, always
The battery is a wear item, and it can burn. The pack is not user-replaceable and degrades over 2-4 seasons, you will retrieve and recharge it near-daily, and cordless robots are the ones behind the CPSC's ~22,000-unit recall. Charge it away from flammable surfaces and never store it wet.
Dealbreaker? Runner-up №1 is corded — no battery, no fire risk ↓

Adjacent verdicts — same method
Traps — this verdict avoids
The charging fire
Cordless robots run on lithium-ion. The CPSC recalled roughly 22,000 Aiper Elite Pro units for overheating and short-circuit, and individual charging fires have been reported. Poolbots reports never encountering a corded robot fire.
The suction gap
Battery robots push roughly 2,000 GPH through coarse mesh screens. Corded robots push 4,000-4,500 GPH through 2-micron NanoFiltration. Same price no longer means the same clean.
Phantom coverage
Quoted square footage and pool-length ratings assume a rectangular inground pool. Freeform shapes, steps and sun-ledges cut real coverage, and several cordless units are reported to get stuck on steps.
