How it differs in this comparison

Limitations and safety boundaries
- A product-page or listing claim is not a substitute for the exact manual’s surface and safety limits.
- Backup-battery or power-off protection must not be treated as cordless cleaning runtime or fall-proof protection.
- Exterior work requires a stable indoor tether anchor, a cleared area below, suitable weather, safe retrieval, and continuous supervision.
