Laundry & Cleaning / robot vacuum
eufy (Anker Innovations) RoboVac 11S MAX (T2126)
D0 No Radio — No radio at all. It cannot phone home.
The unplug test
Nothing changes, because the robot never had a network connection to lose. Press start on the unit or point the infrared remote at it and it cleans a room, then returns to its charging dock on its own. There is no app, no account, and no cloud step anywhere in normal operation — scheduling is done with the remote's own buttons, stored on the robot itself.
Why this tier: Manufacturer's own comparison chart marks this model 'Wi-Fi Connected: —' and 'Works with Amazon Alexa: —', and states control is via an included infrared remote only, with no companion app. Infrared is not an intentional RF radiator and needs no FCC grant. The sibling control confirms it: Anker Innovations (FCC grantee 2AOKB) files grants and EU declarations of conformity for its Wi-Fi-equipped sibling model, the RoboVac 15C MAX (T2128), but no FCC grant exists for this model (T2126) under the same grantee.

Where to buy
Open questions
- No internal teardown/photo evidence found confirming the absence of a Wi-Fi chip on the board itself; the conclusion rests on the manufacturer's own comparison chart and the absence of a matching FCC/EU radio filing rather than a physical inspection.
- Confirm current-year production hasn't quietly added Bluetooth for remote pairing only (some budget robot vacuums use BLE solely to bind a physical remote) — not mentioned in any source found, but worth checking a recent teardown if one surfaces.
Sources
Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.

FCC grantee search for Anker Innovations Limited (2AOKB, 714 filed grants) confirms this manufacturer files FCC grants routinely for its Wi-Fi-equipped and Bluetooth-equipped products (power banks, headphones, cameras, and other RoboVac models such as the T2107/T2104 lines). No grant under this grantee names model T2126 (RoboVac 11S MAX), establishing the sibling-control absence — the connected sibling T2128 (RoboVac 15C MAX) has a published EU Declaration of Conformity for its Wi-Fi module while T2126 does not. — accessed 2026-09-02
