Laundry & Cleaning / steam cleaner

McCulloch MC1275 (Multi-Use Steam Canister)

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

Nothing changes. Fill the internal water reservoir, plug the unit into a wall outlet, and flip the lighted on/off switch. A light tells you when the water has heated enough to produce steam, and a trigger button releases it. There is no Wi-Fi, no app, and no account step anywhere between plugging it in and cleaning.

Why this tier: Manufacturer owner's guide describes only mechanical controls (a lighted on/off switch, a steam-ready indicator light, a steam lock switch, and a trigger-style steam button) and lists no WiFi, Bluetooth, app, or connectivity of any kind. The manual's own FCC Consumer Advisement is a Part 15 unintentional-radiator disclosure ('this equipment may generate, use and/or radiate radio frequency energy') covering ordinary motor/heater electrical noise, not an intentional-radiator grant — this is the opposite of evidence for a radio and directly supports D0 per the FCC heuristic.

Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.
